IX Underquilt - DIY

[sclittlefield]

Here is a quick and easy pattern to build your own a 3-Layer Insultex Underquilt. I wish I had dejoha's illustration skills, but I don't. You'll have to settle for this. :(

Insultex (IX) requires that the layers not be "squished", but rather hang loosely. The small gap between layers (and it can be very very small and work effectively) minimizes the heat transfer, allowing the Insultex to perform at it's best. The differential cuts on this quilt design force those gaps, so no matter how tight you pull the quilt up under you, the layers will not compress.

I have put this together as an average size - modify to your needs, longer or shorter, increase or decrease the width. The picture is a general guideline, but I have found this particular design to fit very well under a hammock and work effectively.

14902

Materials:
4yds Insultex
3yds Shell material (unnecessary, but I prefer 1.1oz ripstop to add durability)
20ft 1.5" Gross Grain (channels)
24ft 1/8" shock cord (suspension)
3 cordlocks (suspension adjustment)

14903

Directions:
1. Cut out the (3) raw sized panels of Insultex, as seen in the drawing.

2. Mark your V-cut-outs (aka-pleats). A sharpie works well.

3. For each V-pleat, fold in half the long way, and sew your lines together (you can cut the flap out or leave it, doesn't matter much either way). When you're done, all three layer pieces will have equal lengths and widths - 42" wide and 60" long - by these specs offered.

4. Shell Material Sub-Directions: Shell material is useful for adding durability to the Insultex, but it also adds weight. One good option is to add shell material only to the outside, as the inside will be against your hammock and be protected.
--4.a. Cut and sew to the same pattern as the corresponding IX layer.
--4.b. Fold V-pleat over after sewing and sew flat to fabric (similar look to a flat felled seam).
--4.c. When sandwiching layers together, be sure the proper side of your shell piece will be facing out.

5. Sandwich all layers together in order. Use lots of pins here, as the differentially sized layers will fight each other.

--Bottom Shell--
--Bottom IX--
--Middle IX--
--Top IX--
--Top Shell--

6. Sew the perimeter of your quilt, approx. 1/2-5/8" in from the edge. If you sew too close, you may find you don't get through all layers as some shifting may occur. If you've sewn too far from the edge so that the gross grain will not cover your thread, feel free to trim to approx. 1/2" from your sew line.

7. Cut (4)1.5" Gross Grain lengths to the height (2 pieces) and width (2 pieces), plus 2 inches. For example, the width is 42", so cut (2) 44" long pieces of gross grain. For a finished edge, fold the ends in, or heat seal with a candle or lighter.

8. Fold Gross Grain in half (long ways, so the 1.5" gg is now 3/4" wide), pin pieces to corresponding perimeter edges of your quilt, and sew in place, being sure you are sewing through all layers. Sew two parallel lines for added durability.

9. Use 36" of shock cord running through each of the short edges of your quilt channels. Sew one end of shock cord to the end of your channel, and use a cord lock at the other end for adjustment (Be sure to use a good knot on the end of the shock cord so it doesn't slip out of the cord lock). Alternately, you could put a cord lock on either end if you don't want to sew the shock cord in place. This will require two extra cord locks.

10. Run the remainder of your shock cord through one long channel, and back through the other long channel. Slip the two loose ends through your last cordlock and tie a knot. (Heat seal your shock cord with a candle or lighter to keep the sheath from fraying.)

11. Place the shock cord over the end knots of your hammock and use the cord lock to adjust. The under quilt will be able to slide back and forth along the channels for easy positioning.

Notes: Insultex does not stuff well, but it does roll well. Fold and roll your quilt, rather than attempt to stuff it into a sack. This will save a lot of space.

[Redoleary]

Very cool. Nice instructions. Thank you very much for sharing.

[dejoha]

I love it! No need for my goofy illustrations -- these are clear and perfect. Now, all I need is some IX! :)

[UncleMJM]

Great instructions, now all I need to do is find some IX and get to work.

[bigbamaguy]

Great another DIY project, where to get the IX......................

[RootCause]

Beautifully done, Mr. Littlefield! Quite often, simple is harder to achieve than complex!

[BillyBob58]

Yes, very nice, thank you. Question: If the inner layer is IX and "pulled snug" against you, do you loose the insulating qualities of the inner layer of IX? If the innermost shell layer was nylon, all 3 layers could hang with a very small air gap from the snug fitting nylon. Of course, it adds weight, but might also increase durability while improving warmth( due to allowing air gap with all 3 IX layers).

[Crog Welly]

Can get IX from Tree to Tree Trail Gear.

[JerryW]

Well done! This should make it easy for anyone to try their own IX UQ.

One option would be to just use the nylon to cover the outside and leave the inside raw IX saving a small amount of weight. EDIT: Sorry, just noticed Scott already mentioned this.


Question: The big box lumber stores all sell foam sheet meant as an underlayment for wood flooring. It APPEARS to be the same foam, just minus the sewn-on scrim layers of Insultex. Does anyone have an opinion as to whether this would work equally as well as IX?

If so, it would make the raw materials a lot more accessible to a lot of people. I already have my own stash of IX, but I know it's getting more difficult to obtain.


Jerry

[exdiver]

I have left-over underlayment, and have checked both or local stores, all I can find has polyethylene on one side. This makes it much heavier and non-breathable. Anybody find some without?

[scum]

You sir are my hero. Simple is better imo and these instructions come accross as diy starter friendly enough that I pulled the trigger and ordered some to give it a try. Mind if I ask how much this weighs in the end and how tightly does this pack (roll) down? I'm imagining it being equivalent to my poncho liner UQ. Is that a fair estimate?

I'm debating tweaking this and sewing the IX into my PLUQ since the channels/cord etc would already be setup. Any opinion on whether that's a bad call.

I think you'll find that the top IX layer will need to be snug up against you for that initial warmth - if it's spaced out with some differentially cut nylon, I think (and could very well be wrong) that heat would more easily 'slip' out the sides. You won't be 'smooshing' the top layer anyway, as it's suspended by shock cord and fitted to the curvature of the hammock - as you move, it will move freely enough.

Jerry

Yes. It appears to be the same thing. And it is very similar, thought not quite the same thing. I don't think it will work equally as well, but I do know it will work well - I've done it (not with underlayment, but with the microfoam used in shipping large screen tv's), and it worked. It's bulkier and heavier, but could be more obtainable.

[MAD777]

Scott, these are excellent intructions! Definitely worthy of a "Sticky!"

[JohnSawyer]

The foam underlayment I've seen is much thicker than the poly foam that IX is made from... maybe 2 layers are enough?

I have some of this foam that's much thinner, it was used to pack a new casio keyboard! (Thanks to my daughter Bookworm for having a b-day and wanting a kb!)

Any idea how low you can go with this UQ?

[dandeman]

hey guys, i have been surfing the web trying to find where to buy insultex, but i cant find anything about price or where to get it...can you all direct me??
Thanks. Dan

[PuckerFactor]

You can find it at Tree to Tree Trail Gear, one of the gear makers on here. http://stores.tttrailgear.com/-strse-54/Insultex/Detail.bok

[thekalimist]

this gets me stoked. will be ordering IX soon!!

also what kinda temps are we getting out of this design???

[tbctx]

Not sure about the flooring underlay but I remember a thread somewhere discussing the fact that one of the packing ones is basically a non-scrimmed IX. Think MacEntyre was doing some testing on it vs actual IX but don't remember results.

[Hokie Hanger]

I'm trying to do a weight estimate. So far I've got 138" or 3.83 yards of IX at 1.66 oz/linear yard = 6.4 oz. 24 ft or 8 yards of 1/8" shock cord at 0.2 oz./yard = 1.6 oz. That gives us 8.0 oz. so far. Does anyone have a good weight per foot for the 1.5" grosgrain?

[NCPatrick]

Very nice instructions! Thanks for posting them.

[Lonely Raven]

Yes. It appears to be the same thing. And it is very similar, thought not quite the same thing. I don't think it will work equally as well, but I do know it will work well - I've done it (not with underlayment, but with the microfoam used in shipping large screen tv's), and it worked. It's bulkier and heavier, but could be more obtainable.

I just installed a bunch of monitors at one of my job locations. I collected all this fine microfoam sheets and made a pillow out of it. Weighs very little, and is *very* warm.

[patermagnus]

Just what I was looking for. Do you think this would work with a Warbonnet Blackbird?

[ewok]

How would a layer of this work to augment a HHSS foam pad?

[sr1355]

Does anyone have a temp rating for this setup.... What are the advantages and disadvantages versus a down UQ.... I'm planning on making an UQ this winter and wondering which direction to go....

This looks very simple to make which is a huge plus....

[scum]

In his instructions, Sclittlefield states an IX quilt w/ 3 layers should be good to below freezing for most.

Opps.... My bad..... Thanks...

[ice man]

Is it really necessary to use 3 layers? or will just one do ya? I been thinking real serious about using insultex, since it's promoted as being God's gift to hammockers. I figured on IX, and then have an outer layer of camo nylon, but the no. of layers of IX is a big question. I'm not wanting to go below zero, just down to freezing. Anyone have experience with this wonder fabric? Time for a sales pitch here.

[dejoha]

IX is not much more than a good vapor barrier, but the pin-hole quilting gives a moderate amount of breathability. I think my IX UQ has 2 layers and it has been good to low 50s, maybe upper 40s.

[ice man]

I have a down "throw" or whatever ya call it for couch-warmer-watching-tv blanket. Maybe that would do. If it were cut down to "looks about right" size and an outer layer of camo nylon sewn on to build a UQ outa. Still scheming an' dreaming. Insultex has me intrigued, tho.

IX is not much more than a good vapor barrier, but the pin-hole quilting gives a moderate amount of breathability. I think my IX UQ has 2 layers and it has been good to low 50s, maybe upper 40s.

I have continued testing a 2 layer IX UQ ( NO shells, just IX). Fit is absolutely critical, though it is with several dif types of UQs. At first, it seemed to me that no way was I going to be able to get under high 50s. But lately I have done much better, though high 30s may be a little beyond me.

I was in the Sipsey a couple of weeks ago and the low was mid to high 40s. Plus, about 0400 the wind really picked up and I did not get much wind block from my HH tarp. Basically, I made it through just warm enough, but not toasty. Some time during the night ( also maybe ~ 0400? ) I realized I was definitely going to make it, but decided to add my CCF torso pad, just for luxury warmth, which it provided.

This weekend ( Oct, 22/23 ) at fall Creek Falls,TN the temp fell to 39F. Most of the night I was OK, but near dawn I was not quite warm enough. I could have made it, I did not shiver and was def able to sleep, but I was in no way "toasty" most of the night. Once again, about 0430 or so I decided to add my pad. For some reason, I was still not toasty warm, just barely OK.

I am going to keep experimenting, but as of right now I would not choose just 2 layers of IX if I knew lows were going to be below 45, though I have pushed it a little beyond that without being too uncomfortable.

Two things to consider in the above testing. This UQ was designed specifically for a HH Explorer. I used it on a Claytor No Net both times in case I needed to add my torso pad. It fits me better on the HH, and thus might be a tad warmer on the HH. ( plus, I am looking forward to trying it as HH OCF pad augmentation/replacement)

Second, mine has no shell at all. A shell might add a few degrees, and more than a few if there is an inner shell providing more of a differential cut and preventing the IX from being pulled tight against you. Or, maybe not.

[thekalimist]

what is the width of the IX sold on TTTG?

[Gqgeek81]

A few thoughts and questions....

How much did the finished product weigh and how big is it rolled up and packed?

What if you build the shell sort of like a pad extender so that you can go 1-3 IX layers as the trip requires? Is this doable?

It sounds like those that already have a UQ, especially a summer or 3 season one may be able to slip in a layer or two of IX to make it a 4 season setup. For that purpose would you bother adding a shell to the IX or can we just slide it in between the UQ and the a hammock?

I have a 1/4" gossamer gear pad I use during summer trips mostly for the bug protection. Do you think a single layer would accomplish this?

The remarks about using packaging foam confuse me. If closed cell foam in general works this well then shouldn't the blue wally pads be good for arctic expeditions? My humble instinct is that either the marketing is over hyped or there has to be something else going on here other than just 'foam'
It is interesting to see this develop though.

[MacEntyre]

what is the width of the IX sold on TTTG?
IX is 60 inches wide

[thekalimist]

IX is 60 inches wide

thanks Mac!

[MacEntyre]

...would you bother adding a shell to the IX or can we just slide it in between the UQ and the a hammock?
With or without a shell, you can just lay IX inside your UQ... it works very well!

That is how the Molly Mac Gear nestable IX Inserts work. They are not covered, and just lay on top of the UQ, underneath the hammock.

:thumbup:

[MAD777]

Remember that IX must have an air gap to be effective. Therefore, you wouldn't want to pull it up tight against the bottom of your hammock or underquilt. I think the most effective way to use it is to sling it under your underquilt, like a loose weathershield. But, seal up the both the side and end edges to eliminate drafts. This way, it will act as an insulator, windscreen and weathershield. In this configuration, even a single layer would be effective. More layers, with a gap between each, would multiply the affect.

Don't squish IX between your hammock and underquilt. It's nearly dead weight then.

[MacEntyre]

You're right, Mad777... but it only needs a tiny air gap, perhaps 1/16". If your slack off your UQ suspension just a wee bit, IX works great between the UQ and the hammock. It doesn't do well between the layers of a double layer hammock, though. :mellow:

[Gqgeek81]

To create the air gap I'm pondering a layer to tulle between the IX layers if the gap can really be that small.

It also sounds like a very small draft tube might help get the fit right if trying to strap it up under the hammock, although it might making rolling it up a bit awkward too.

Or maybe it just needs a skirt around the IX with shock cord sewn into the edge to prevent any drafts so it acts like a giant upside down beanie on the bottom of the hammock. You'd still need tie outs to hold it on of course.

That's exactly the idea that I was trying to describe! Excellent visual!

[sclittlefield]

How much did the finished product weigh and how big is it rolled up and packed?

16.4oz - that's with shell material on both sides and extra shock cord and cord locks.

Here's a picture with it next to a Crowsnest and a Climashield UQ (46x60). The Down and Synthetic UQ's can squish down a bit more in your pack than the IX can.

What if you build the shell sort of like a pad extender so that you can go 1-3 IX layers as the trip requires? Is this doable?
Yes, this is doable. You'll want some system to keep the inserts in place, as they could easily bunch up - velcro tabs at the corners would be a simple solution.


It sounds like those that already have a UQ, especially a summer or 3 season one may be able to slip in a layer or two of IX to make it a 4 season setup. For that purpose would you bother adding a shell to the IX or can we just slide it in between the UQ and the a hammock?
I have found IX to work best on the outside of your synthetic or down insulation - it will need to be sized and hung so that it does not 'squish' your other insulation. I think a layer or two if IX is an ideal way to push a 2 or 3 season quilt to a 3 or 4 season quilt.


I have a 1/4" gossamer gear pad I use during summer trips mostly for the bug protection. Do you think a single layer would accomplish this?
I would choose 2 layers, but yes, sized and suspended properly, definitely.


The remarks about using packaging foam confuse me. If closed cell foam in general works this well then shouldn't the blue wally pads be good for arctic expeditions? My humble instinct is that either the marketing is over hyped or there has to be something else going on here other than just 'foam'
Microfoam works well, perhaps just not as well. I think your humble instinct is right on the money. In my opinion, IX is both overhyped (read the advertized "one layer Insultex protects a person to -13F. I question that. (http://idigear.com/insultex.php)) AND there is something going on that makes it perform better than simple micro-ccf.

If that were the case they'd be able to put the Aerogel makers out of business and we'd all be lining our walls with the mess.

So it sounds like I can potentially swap out my blue foam pad for a rolled up IX underpad for very close to the same weight, maybe a few ounces more, and gain quite a bit in cold comfort.

And for a lot less money and hassle than sewing up a DIY down UQ.
Interesting.

[MacEntyre]

If that were the case ...we'd all be lining our walls with the mess.
Insultex has been approved for use as housewrap, like Tyvek but insulating.


So it sounds like I can potentially swap out my blue foam pad for a rolled up IX underpad for very close to the same weight, maybe a few ounces more, and gain quite a bit in cold comfort.
They are apples and oranges... IX weighs significantly less than blue foam, but you can lay on foam pads, unlike IX. A blue foam pad is a far superior insulator.


And for a lot less money and hassle than sewing up a DIY down UQ.
Just so! IX is PE foam fabric. It won't gather quite as well as we would like, but you can get around that using darts.

IX and Down are also apples and oranges. I have not found the warmth to weight equation to be as good with IX as it is with Down. And down squishes so much nicer in my pack.

That said, on a lower budget, or as a quilt temp booster, or even for synthetic-over-down fans, it gets two thumbs up in my book.

[Roadrunnr72]

New to the Thread Injector, but you can sew threw 3 layers of IX, with a standard machine? Nothing special about it?

[sclittlefield]

Nope, nothing special to it. Easy as pie. Just use lots of pins to keep the layers in sync.

[silentorpheus]

So if I have a synthetic diy UQ and want to whip up one of these to use as a supplement when it gets real cold, do I want it sized to go over my UQ, or for this to go against the hammock, and the UQ below that? Scott, you seem to suggest that over is better, Mac seems to suggest under (or at least suggests that it works well, not necessarily that it's 'better').

Under would be easier to size, since I wouldn't have to do much about making sure it doesn't pinch my quilt, so no extra planning or calculations needed. :confused:

I'm not truly convinced that either way is better. So long as you're not squishing the insulation of either system, I'm half ready to guess that it'd be 6 in one and half a dozen the other. I definitely wouldn't write off either method.

[scum]

I've got my IX & plan to start on this soon. I have a question about the differential cut. When it comes time to sew them together, on any given edge I'll have 3 different lengths to line up. How do you sew these together? At some point is there some 'bunching' that happens on the longer length so that the corners can all line up? Maybe a bit of stretching on the inner layer - or both? Seems like bunching would kind of defeat the point. Do you just center the layers and not try to line up the corners? :confused:

I'm sure I must be over thinking this since everything I've looked up says its simple to sew up but I'm not finding much for sewing instructions to help me visualize this.

Also, since I'm already over thinking things, shouldn't the inner liner be cut slightly smaller as well in order to prevent the innermost insultex from getting compressed? And finally, any benefit to adding some darts along the long edge similar to the Baby Orca?

Thanks again!

[Rat]

Scum, I think all of your questions were answered in the original post. Here it is for posterity.

If you've sewn too far from the edge so that the gross grain will not cover your thread, feel free to trim to approx. 1/2" from your sew line.

7. Cut (4)1.5" Gross Grain lengths to the height (2 pieces) and width (2 pieces), plus 2 inches. For example, the width is 42", so cut (2) 44" long pieces of gross grain. For a finished edge, fold the ends in, or heat seal with a candle or lighter.

Alternately, you could put a cord lock on either end if you don't want to sew the shock cord in place. This will require two extra cord locks.

10. Run the remainder of your shock cord through one long channel, and back through the other long channel. Slip the two loose ends through your last cordlock and tie a knot. (Heat seal your shock cord with a candle or lighter to keep the sheath from fraying.)

11. Place the shock cord over the end knots of your hammock and use the cord lock to adjust. The under quilt will be able to slide back and forth along the channels for easy positioning.

Notes: Insultex does not stuff well, but it does roll well. Fold and roll your quilt, rather than attempt to stuff it into a sack. This will save a lot of space.

Currently, IX can be purchased here: TreeToTree Trail Gear (http://stores.tttrailgear.com/-strse-54/Insultex/Detail.bok)

In reading through the instructions, it looks like the inner layer of IX isn't compressed due to the differential 'bathtub' shape of the other layers; even though the perimeters end up all the same. This is a result of the darts, which, I think, you mentioned were needed.

[scum]

Thanks. I appreciate the response!I've read it thoroughly, and you're right, it does answer the question of whether the inner layer of insultex will be compressed so no need for tweaking beyond the given instructions.

However, my main concern is the how-to on sewing the differential cut. There's a difference of 4 inches between the inside and outside layers along the top/bot edges that need to be made up somewhere/somehow.

In other words if I'm sewing on the top edge and start at a corner, when i get to the end of the edge at the next corner, the inside layer is going to be 4" short. Unless I pleat/bunch the outside layer somehow or split the difference and make the inside layer 2" short on each side?? Am I just worrying for no good reason and the 4" will easily work into the ~4 feet of edging?

Sorry for being so dense on this, but I haven't sewn anything more complex than patch work for clothes. I'm sure it's painfully obvious to most but I just want to be sure to get it right. I'm really just looking for, 'don't be paranoid, let it bunch up a bit, sew it up and be done' or some other tip for getting it done better if one exists.

Thanks!

[MacEntyre]

Scum, start your run at a corner, and stop before you get to the middle. Start at the other corner, and when you get within a foot of where you stopped the first run, start pleating the edge. Just fold the edge to take up an inch and a half or so, and stitch right over it. Check to see if the edge lengths are the same. If not, add another pleat a couple of inches further down. Eventually, you will take up the extra 4" of length.

If I had a differential of 4", I would just add another dart. Either way, you have to adjust with pleats to align the edges. Just make sure your adjustments are between the corners. I do this on all four edges. If you always start at the corners, the corners will always align.

Brilliant! See, I knew you guys would have some wisdom for me. Thank you very much for the tip.

If I can get ahold of the thread injector, I'll be working this over the weekend and have some pics for ya. I have a planned campout next weekend where the temps are looking to be in the mid 20s to low 30s so I gotta get this done quick!

[scum]

Here's my results. I'm very happy with how this turned out. I certainly learned a lot as I went. It won't win any contests for straight seams, but overall this was much easier than I expected it to be. Hardest part was threading the stupid needle. :D

Hopefully, I'll have a chance to test this out in the cold next weekend.

The final product:

View of the shell. I used a poncho liner cut to size of the outermost IX. It's what I had available and I'm hoping this will give even more boost to the temps I can use this for.

Here's a couple of the intermediate steps. I'm cheap, so I used what I had available which means green thread on the white ix but it works just the same. I folded the darts over and sewed them flat rather then cutting them out as well.

scum that is really great looking

Very nice looking IX Quilt Scum. Did you find that after darting the material the edges lined up pretty well? I also like the addition of the poncho liner; Roz already wants me to do this to hers!

Be sure to report the temps and warm of the IX Quilt after next weekend. Every one is jonesing for good temperature info on this stuff as it is so new.

Again, great job!

[scum]

Things lined up very well actually. There was very little need for pleating as I had feared. As the instructions state, lots of pinning helps. Kudos again to Sclittlefield for the instructions.

The campouts still on so hopefully I'll have some good numbers. I'll be car camping so I'll be able to push the limit a bit with the option to supplement if needed. Here's hoping for cold temp...

I've got my IX & plan to start on this soon. I have a question about the differential cut. When it comes time to sew them together, on any given edge I'll have 3 different lengths to line up. How do you sew these together? At some point is there some 'bunching' that happens on the longer length so that the corners can all line up? Maybe a bit of stretching on the inner layer - or both? Seems like bunching would kind of defeat the point. Do you just center the layers and not try to line up the corners? :confused:

Once you sew the V's together, all perimeter lengths are equal. The 48" wide piece has 6" removed (in 2-3" pleats), giving you 42". The 46" wide piece has 4" removed in one pleat, giving you 42". And the 44" wide piece has 2" removed in one pleat, giving you 42". Following the instructions, all pieces will end up being 42" wide and 60" long.

By my math,
48-3-3=42"
46-4=42"
44-2=42"

:)

So if I wanted a 48" wide UQ, I'd need to start with 54-52-50?

[sclittlefield]

Yup. Adjust to suit.

You can also change the darts/pleats dimensions as well:

more fabric removed from edge = more curvature (ex. 8" removed instead of 6")
less fabric removed from edge = less curvature (ex. 4" removed instead of 6")

Good to hear. I was hoping to make a full length one that can function as a weathershield for my UQ. If that works, I could also sew a 4th layer of IX (60X78) along the shock cord on one side to provide a hammock sock when draped over the hammock ridgeline or as a vapor barrier to encase a down UQ on top as well. The top should hold in a decent amount of heat and since the ends are not sealed on top condensation should be reduced.

[scum]

My forecast is calling for mid 30* lows tonight with 50% chance of 1" of snow. Think I might have to try the backyard hang tonight to give this a prelim test. Here's hoping my kids steel pole swingset will hold my hammock (if you have bad experiences with this, nows the time to tell me)... :scared:

I know the IX doesn't lend well to stuffing, but is there any risk to cramming/folding this thing into a compression sac and cinching it down? Will it damage the IX to be compressed like that or should I just be content with a tight roll-up?

I like to fold, then roll, then stuff, then compress. You won't hurt it!

[scum]

Gave it whirl last night. Starting temps were 34*. I had trouble getting a good fit (learning curve with an UQ). I couldn't convince the wife to stand out there and tell me if I had gaps so I had to wing it a bit. Once I got it sealed up, you could tell. It takes about a min and the cold just starts to fade away. Then it was easy to feel the remaining trouble spots. I struggled with a cold spot under my shoulders but after some more readjustment got it dialed in. Any tips on suspending this appropriately would be appreciated. E.g., since it's differential cut should I be concerned about tightening it up too much or should I just crank it up? I think part of the problem is I was forced to hang at a pretty steep angle and had quite the banana shape going on, so the ends of the UQ couldn't quite compensate enough to stay snug.

Some info here. I used nothing to supplement under me. I had a sleeping bag TQ and wore my typical winter sleeping attire (long johns, sweat pant, sweat shirt, wool socks and knit hat). I was warm, but not toasty. I was certainly much warmer than the outside temps.

I woke up about 3am - temps were now about 30*. I was just as warm as when I fell asleep. But, my hammock setup consisted of stringing up using my kids swingset and was not comfortable at all and I just couldn't get settled in again. So I bailed.

I'm convinced that I could ride out temps down to the high 20s as I was setup last night. In a real campout hang, I will be using more to supplement. I'll have my sit pad under my feet (which did get a bit cool since they were beyond the UQ - but not bad) and I'll have either a water bottle or a couple of hand warmers plus probably my baklava. With those, I'm sure I could be comfortable in the 20s. If there's a chance of dipping into the teens, I'll be bringing a pad just incase I need to supplement

Biggest thing for me is I need to get the hang (get it?) of the suspension and get it dialed in better. Overall, I'm still satisfied with this UQ. As usual, YMMV with what temps you can take this down to.

Great report. It's good to hear from others who've put it to the test. I bet, once you get the fit dialed in just right, that it will be just fine at 30*. If you can go 20*'s, that would be amazing.

I tend to sleep in the fetal position in a hammock, so the 60" length is perfect. Some of you folk may want to lengthen it a bit, and if you do, may want to add some darts to the long sides to help with the curve.

[thegreatjesse]

Just ordered the supplies to make my IX underquilt! This is my first DIY project, so I'm hoping it is as easy as scum made it look! I got the IX and ripstop from TTTGear and the rest of the materials from Quest Outfitters, so big thanks to these outfitters.

Quick question though, any suggestion to make this work well at around 20* and possibly into the teens? I have pads, but would like to do without one, if possible. I'll also be using a Marmot 20Deg bag as a TQ, so I could potentially zip up, if the need arises. Any advice?

Thanks!

[scum]

I made my shell using poncho liner hoping to get that extra boost into the 20s. Haven't had a chance yet to see but I'm hopeful. Worst case, I'd say an extra layer of IX that you could either slip between the hammock and UQ or even under the UQ. I suspect, it would be best under since the differential cut of the UQ will already be tight under the hammock and you want to avoid compressing the materials.

Keep in mind also, my 30* test was without any supplement. Given a hot water bottle or a couple handwarmers can boost quite a bit. Also, my tarp setup was not ideal for cold weather. I had to hang it very high so in all respects it provided nothing for heat retention. It's been mentioned before that a well hung tarp with the 'doors' pulled in can make a significant difference. Good luck.

[scum]

Per the discussion in this thread (http://www.hammockforums.net/forum/showthread.php?p=351049#post351049 ), I decided to add some draft tubes. It's something I toyed with in my head even before I started this project. This just convinced me to try it. It was a do as you go type project and I've only completed one side but wanted to share what I have so far.

I stole the idea from my sleeping bag draft collar which does a good job of 'standing up' and filling in the gaps around my neck/shoulder. I didn't have time to hang it and test under my hammock yet but hopefully will this weekend.

The pic doesn't show it well, but the draft tube is standing straight up roughly 4-5 inches at the center. More than enough to fill any gaps imo.

It's sewn at the perimeter of the UQ. The inside edge 'floats' but has the drawstring in that edge to pull it tight and force it to stand up when wrapping around the hammock/body.

This was done using my left over IX and poncho liner. I'll have to take the exact measurements but essentially a ~5" diameter tube of poncho liner with IX lined inside. I sort of pleated the left and right edge a bit to help force it to 'pop up', but really the drawstring handles that just fine so these may not be necessary. There are no darts or other shaping, just a tube the length of the edge essentially. The string is 550 and it's sewn in both ends and exits in the middle. This will add some weight, but it's acceptable to me for the comfort of having a tight fit no matter the position I sleep in or the angle of my hang. Like I said, I just copied how my bags draft collar works. I'm very convinced though that this will seal up my UQ no matter the situation. At the least, it will make it less critical that this be exactly at my shoulders for a good seal. Once I get the other tube on, I'll try to get a hang in with pics for proof.

[dejoha]

Nice job, Scum, on the draft tubes -- looks great! I can't wait to hear how well it performs!

[scum]

I still haven't been able to hang it an test the seal with the new draft tubes but wanted to throw out a fair warning about using a poncho liner for a shell. I weighed mine and it's 30oz almost exactly. The scale I used is questionable, but accurate enough I believe for a ball park. So, if your concerned about weight, keep it with only the ripstop nylon shell. Just a fair warning...

[thegreatjesse]

I'd love to hear how the draft tubes work, when you get 'em tested. If I'm correct in my estimations, my UQ will come in around 9.5 - 11 oz, which is nearly half of what my CCF pad weighs. If your tubes work well, I would definitely try them on my UQ also, and I think I can afford a bit of weight. Now, to figure out how to sew!

[lilricky]

Tree to tree is offering IX for $6.50 a linear yard, but how wide is their roll of IX?

[JDShearer]

IX is 60 inches wide

This was mentioned earlier in this post.

[scum]

I tested this UQ last night. It performed well beyond my expectation. I started at 13*F temps. The draft tubes sealed things up perfectly. In order to be able to lay on my side without gaps, I strung up the feet end similar to how a 'triangle thingy' would. Worked perfectly. I plan to make/buy a couple to round this thing off and make it fool proof. The only issue I had was adjusting the UQ so it rested correctly at my shoulders. Once I got it setup, it kept me perfectly warm ... until I had to bail.

About 3am, I woke up cold - too cold. So I decided to bail to the nearby cabin. When I got out, I discovered why I was suddenly cold. My hammock suspension had stretched to the point that the bottom of my UQ was inside the snow! Considering my UQ was inside the snow, it was relatively warm.

The tree I had slung to on one side was too big for my tree straps so I had a makeshift strap made from a tow strap (which apparently stretched). The temp when I had to bail was ~8*. I think if I would have stayed out of the snow, I would have been fine through the night!

Final results for me, this will At Least get me through the teens and may handle the single digits.

The 'specs': I had a 0* bag as a TQ, a poncho liner as an overcover (worked great to create a micro climate but built up condensation and ice), thermals, wool socks, a heavy sweatshirt, a hat and a couple of strategically placed hand warmers. Basically, the usual hard winter setup. There was little to no wind and about 16" of snow :)

[thegreatjesse]

Awesome test! That's incredible, this stuff is like miracle insulation.

I just finished my IX UQ, didn't have a chance to try it overnight yet, but I put it on my hammock and got in for about an hour or so, and it is awesome. I had no trouble cinching up the shoulders, and the foot-end seems okay, but I was kind of curled up and without a foot-pad, so I can't say for sure. Ambient temp was 29, I was in a down sweater with a t-shirt and Dickies, athletic socks and a fleece hat. I was totally comfortable, even without a TQ, for about an hour, and I only got up because I wanted to take some pics.

I have to re-sew a spot on the shell, because I trimmed too close and the stitches ripped out, but other than that I didn't run in to too many issues. Running the shock cord through the channels sucked, but it was my own fault for sewing the grosgrain so close to the edges. This was my first big DIY project, aside from a gathered end hammock I made, and I'm really happy with it. The thing ended up weighing 14.8oz, which is more than I wanted it to, but I think I'll live. Can't wait to try this thing out!

[Hokie Hanger]

Does anyone have any idea what a 2 layer UQ built like this might be good for temperature wise?

[scum]

Seems like I've read somewhere that the Molly Mac underquilts are 2 layers?? Might do a few searches and look at the results from his gear.

[MacEntyre]

I have been comfy using a two layer IX UQ without a nylon cover, all the way to freezing on more than one occasion. I'm not a cold sleeper. Most folks will be able to get to 40*F.

I have a three layer 5-in-1 Jerry Chair UQ (3 layers of IX, nylon covered both sides) that easily takes me below freezing. I'll find out how far below freezing one day soon!

- MacEntyre

[canoebie]

I have had similar experience to MacEntyre. I have two layers and with a pad have been down to 11 degrees and warm. I think this stuff (IX) really shines as an UQ.

[JohnSawyer]

Thanks to Sclittlefield... I finally used my IX I bought some time ago...

Made my UQ to specs with one difference: I cut the shell wider and instead of binding the edges with GG, I wrapped the 1.1 ripstop over the top edge and sewed through, using the ripstop as end and side channels.

The only problem I have is that as I shift about, the quilt scrunches up lengthwise, and shortens up a bit, lowering away from the hammock in the process. A few minutes later, my butt gets cold... I like the fact that there is shock cord along the sides, as it makes a very good seal. I might just lock the shock cord in the side channels with a few tight stitches and see how that works.

I have a real long hammock (11') so I approximated a triangle thingie with a 6' length of cord, and use cordlocks as toggles to hold up the south-end of the UQ. It is definitely warm on my back, but I struggle with getting it adjusted to be warm on my butt. (I have the same issue with my KAQ when it gets on the colder side outside... I'm wondering if I have it Too tight...)

So now I have 3 quilts: KAQ lost river, PLUQ, and a 3-layer IX... I figure I could nest the IX and the KAQ for colder temps. These now give me the option to camp with both my children: my daughter (Bookworm-12) and son (Projects Force at at Distance - 9) though he prefers a different name...

[ChrisH]

Seeing as this stuff needs a small gap in between layers to work effectively, do you think that mesh sewn in between the IX layers would make it more effective? I know it would be a little heavier but it's just a thought.

[MacEntyre]

ChrisH, a differential cut weighs nothing. Just make each layer bigger by an inch all the way around.

What MacEntyre is saying is that the differential cut gives you the air gap you are referring to with no weight penalty: no reason to add anything to get the gap.

I saw on this thread that compressing the XL doesn't degrade the material and its ability to trap air and keep it warm. Did I read this correctly and can it be true? I am so conditioned to protecting insulation from compression that I am not sure I understand this but if true, how wonderful.

I know it wouldn't breath but has anyone tried this idea with a space blanket. It seems that the SB would also hold the air pockets and maybe pack up a little smaller. I have supplemented a synthetic DIY sleeping bag mod UQ with one and had no condensation issues down into the 30's.
Think it would be worth the effort?

has anyone tried using ix as a pad in the hammock. I understand that there needs to be a gap wondered if a fleece throw on top of the ix would work for an air gap

[ChrisH]

Laying on top of the IX will compress it thus removing the air gap needed to keep you warm. It doesn't matter if you have something like fleece in between, laying on it will compress it.

[wildcrafter]

i was of the impression that ix is a closed sell and doesnt compress

Going to 18" on the darts should work just fine, especially with the longer quilt length. Side darts are a good idea. That's how Mac does his designs. I haven't done much with side darts, but I can't see any big negatives.

[MacEntyre]

Going to 18" on the darts should work just fine...
Longer darts would be good for the ends. I make all darts six to eight inches long. There are diminishing returns for long darts, because it's the edges and the fabric near the edges that you want to shape.


Side darts are a good idea.
I dart the ends, the sides, the corners...

I'm waiting on my supplies to arrive, and am anxious to make my underquilt. I want to make 6 foot full 3 layer quilt. My question is should I make the darts longer than 12''? I was thinking 18''. Also should I add some darts on the sides so the quilt won't sag in the middle? I want to end up with a quilt 6 ft x 45, or 48 inches. any suggestions?

First, I would build it they way it is designed because this is a proven method. However, playing with it during the construction is the best part. I would tack a few darts and then pin it up to a hammock and see how it fits with the longer darts before I committed to anything permanent. But I think MacEntyre is right, the longer darts may prove more useful on the ends with the longer quilt. I think this may accomplish very near the same effect as having draw cord channels in the end.

[russmay]

Hay thanks for the the input. I see great minds think alike. When I start,I will take some photos of the stages of building it.

[GvilleDave]

Scott - Thanks for posting the instructions for this UQ! I just finished a slightly modified version w/ 4 layers of IX. The finished size is 66" x 47" and I darted the ends and the sides (but not the corners Mac...). I posted a detailed description in a separate thread under DIY. Also thanks to MacEntyre for his advise and input.

Thanks again for the instructions, tips and inspiration!

Very nice Dave!

[scum]

Scott,
How much does it weigh.

[sclittlefield]

Scott,
How much does it weigh.

16oz. That's three layers of IX, both sides covered with 1.1oz ripstop, 1.5" gg bound, all sides, and shock cord / cordlocks.

[scum]

Sorry Scott, meant to address that to GvilleDave. Thanks for the response though!

Still lovin my IX UQ.

[GvilleDave]

Mine being 66" x 47", 4 layers IX w/ just the outside covered in 1.9 RS weighs in at 24.7 oz w/ suspension complete.

[dandeman]

golly, this ix crap is so expensive to ship aparently!! from trail to tree it is $42 FOR SHIPPING ALONE! on 8 yards of ix....the ix only costs $52 for the 8 yards!! idk, they're shipping cost is a real turn off for me right now, since they advertize it as priority mail...that should cost like $8-15, not $42. someone please tell me that there is a mistake or that us hammock-ers get some super discount.

very cool and lightweight

[dandeman]

ok, so another question: Why use grosgrain for your channels...it would seem to me that just a bit of ripstop nylon would do the trick...and be way lighter and be less of a hassle than buying the more expensive grosgrain separately. IDK, that is just my thought, maybe ripstop would wear out, though that is in an extreme time test. Another Q: is IX downproof?? if so, than wouldnt it make an absolutely outstanding down quilt material, since it would not only have the warmth of the down, but the IX would also have its beloved dead air space. it would seem that it would make a really cool looking quilt that would be just as light as if ripstop had been used, but it would have superior thermal values/properties! AHHH! I now want to make a down quilt out of IX instead of just an IX quilt! this DIY business is so stressing haha!!

Why gross grain? I've done both and I just really don't like the ripstop channels, at least with the lightweight ripstop I use for the shell. It will work and that's the beauty of DIY - you can adapt any design to fit your needs. I'm not sure if they're still doing it that way, but that's how KAQ quilts at least used to be done. Personally, I really like the gg binding.

Yes, it is downproof. I know HammockGear.com has done some experimenting with down and IX. IX is not tough like fabric is though (it's very easy to slice or poke a hole in), so if you don't use a shell material, you'll need to be VERY careful with your gear - VERY careful. Getting a hole or slice in IX alone isn't a huge deal, it's an easy fix - but if it means you're spilling expensive down, it becomes a big deal.

Experiment. Change. Adapt. DIY is fun. :)

[MacEntyre]

IX is not tough like fabric is though (it's very easy to slice or poke a hole in)
My experience is that IX is surprisingly stout... it will stick to things, though, and if you yank it after it falls on a bush, that could cause damage. The part that is exposed is the polypropylene scrim, which is pretty tough stuff. It's just not smooth, like nylon.

[GvilleDave]

On my IX UQ i covered the outside face w/ a 1.9 oz ripstop and cut the ripstop 2 5/8" wider along the edges than the IX. This let me wrap the RS around the edges to form my channels. The only grossgrain I used was for small suspension loops at the four corners. Time will tell how well the RS channels hold up. Worst case if they start to wear I cut off the RS chanels and replace them with grossgrain then... I don't think that will happen though, 1.9 oz RS is pretty stout, but its what I had on hand (left overs!)

Next week I am going to make a PEF Baby Orca with a space blanket layer built in, for TZBrown to experiment with... I have no idea how much the reflective layer will add to the temp rating, but it ought to be significant, like at least 5*F and maybe more.

I couldn't sleep last night, so I started my IX UQ.
Really wasn't ready, as I was still kicking around a few design ideas.
However, I figured I'd just jump in with the plans from this thread and see how it turns out.
Being 6'4" I wanted to do something longer than 60", but with only 4 yards of IX I figured this was probably about the most efficient thing I could do with it.

What I did differently:
-I made 1 inch pleats instead of darts.
48" layer has 6 x 1" pleats at each end. I did not space them evenly. I was thinking that since my shoulders are sort of flat, I'd leave the very middle section flat, and added the pleats out towards the edges a bit.

46" layer has 4 x 1" pleats at each end.

44" layer has 2 x 1" pleats at each end.

I used a 65" x 65" piece of 1.1 oz RS for the bottom cover.
Folded all edges over to make a channel for the suspension bungees.
Also made a wider flap/channel on the long sides to act as a seal. I may put some rolled up IX in them ala draft tubes, or may try something else to give them some volume. Not sure yet.
http://gear-report.com/wp-content/uploads/2011/01/2011-1-Jan-1469-e1295984232537-225x300.jpg
Still have to sort out all of the suspension details.

Likely to use very limited grosgrain on the suspension points instead of running full gg channels for the suspension.
Also likely to leave the top side of the UQ uncovered.

I thought sil was hard to work with, but found IX to be far more challenging to keep lined up properly. The darned scrim wants to slide all over the place! I HATE to pin, but ended up doing lots of pinning (well, lots for me) and still have some of the worst looking seams I've ever sewn.

I installed the first version of suspension on my IX UQ last night, and have some tweaking to do.
Wanted to share something I learned, as it may benefit others here.

My FrankenBird hammock body is Polyester.
I did not cover the top of my UQ, only the bottom.
I found that when I got in the hammock and reached out to adjust the UQ, it wouldn't budge.
That darn scrim that was so slick and sliding all over the place when I was trying to sew the RS nylon cover to the bottom is definitely NOT slick up against the Polyester hammock. It grabs like crazy.

I'm inclined to think that this is a good thing, or at least a mostly good thing.
If the UQ is in the right position relative to the hammock body when I get in the hammock, then the UQ is very unlikely to shift around as I move.
However, if it is not in the perfect position, then I've pretty much get not choice but to get out to make adjustments.

I have not yet finished tweaking my suspension setup, and am optimistic that I'll get the suspension dialed in so that adjustments won't be needed. If I can't get it dialed in, then I'll likely ad a layer of nylon to the top of the UQ to make adjustment from withing the hammock easier.

Hoping to talk pics of the whole setup this weekend. :)

[BigT54]

Here is a quick and easy pattern to build your own a 3-Layer Insultex Underquilt. I wish I had dejoha's illustration skills, but I don't. You'll have to settle for this. :(

Insultex (IX) requires that the layers not be "squished", but rather hang loosely. The small gap between layers (and it can be very very small and work effectively) minimizes the heat transfer, allowing the Insultex to perform at it's best. The differential cuts on this quilt design force those gaps, so no matter how tight you pull the quilt up under you, the layers will not compress.

I have put this together as an average size - modify to your needs, longer or shorter, increase or decrease the width. The picture is a general guideline, but I have found this particular design to fit very well under a hammock and work effectively.

14902

Materials:
4yds Insultex
3yds Shell material (unnecessary, but I prefer 1.1oz ripstop to add durability)
20ft 1.5" Gross Grain (channels)
24ft 1/8" shock cord (suspension)
3 cordlocks (suspension adjustment)

14903

Directions:
1. Cut out the (3) raw sized panels of Insultex, as seen in the drawing.

2. Mark your V-cut-outs (aka-pleats). A sharpie works well.

3. For each V-pleat, fold in half the long way, and sew your lines together (you can cut the flap out or leave it, doesn't matter much either way). When you're done, all three layer pieces will have equal lengths and widths - 42" wide and 60" long - by these specs offered.

4. Shell Material Sub-Directions: Shell material is useful for adding durability to the Insultex, but it also adds weight. One good option is to add shell material only to the outside, as the inside will be against your hammock and be protected.
--4.a. Cut and sew to the same pattern as the corresponding IX layer.
--4.b. Fold V-pleat over after sewing and sew flat to fabric (similar look to a flat felled seam).
--4.c. When sandwiching layers together, be sure the proper side of your shell piece will be facing out.

5. Sandwich all layers together in order. Use lots of pins here, as the differentially sized layers will fight each other.

--Bottom Shell--
--Bottom IX--
--Middle IX--
--Top IX--
--Top Shell--

6. Sew the perimeter of your quilt, approx. 1/2-5/8" in from the edge. If you sew too close, you may find you don't get through all layers as some shifting may occur. If you've sewn too far from the edge so that the gross grain will not cover your thread, feel free to trim to approx. 1/2" from your sew line.

7. Cut (4)1.5" Gross Grain lengths to the height (2 pieces) and width (2 pieces), plus 2 inches. For example, the width is 42", so cut (2) 44" long pieces of gross grain. For a finished edge, fold the ends in, or heat seal with a candle or lighter.

8. Fold Gross Grain in half (long ways, so the 1.5" gg is now 3/4" wide), pin pieces to corresponding perimeter edges of your quilt, and sew in place, being sure you are sewing through all layers. Sew two parallel lines for added durability.

9. Use 36" of shock cord running through each of the short edges of your quilt channels. Sew one end of shock cord to the end of your channel, and use a cord lock at the other end for adjustment (Be sure to use a good knot on the end of the shock cord so it doesn't slip out of the cord lock). Alternately, you could put a cord lock on either end if you don't want to sew the shock cord in place. This will require two extra cord locks.

10. Run the remainder of your shock cord through one long channel, and back through the other long channel. Slip the two loose ends through your last cordlock and tie a knot. (Heat seal your shock cord with a candle or lighter to keep the sheath from fraying.)

11. Place the shock cord over the end knots of your hammock and use the cord lock to adjust. The under quilt will be able to slide back and forth along the channels for easy positioning.

Notes: Insultex does not stuff well, but it does roll well. Fold and roll your quilt, rather than attempt to stuff it into a sack. This will save a lot of space.

Currently, IX can be purchased here: TreeToTree Trail Gear (http://stores.tttrailgear.com/-strse-54/Insultex/Detail.bok)
How cool is that thanks...

[rjcress]

My first test of the 3 layer IX UQ was a success.
I'll post full details later this week, but here's the key points.

Low temp: 24* F, wind was light and variable
Was 36*F when I entered the hammock. Everything warmed quickly and I shed my fleece pull-over and wool socks so I wouldn't sweat.
Woke up a few times overnight and checked temp. Bottomed at 24* and was that temp for about 8 hours.
Above freezing my back was about the perfect temp. Below freezing my back was a touch cool. Not cold, not even chilly... just a bit below perfect. I was never cold and always able to fall back asleep very quickly.
Next test will be with the UQs switched. ie. IX on the inside, fleece on the outside.

other gear:
My DIY Frankenbird hammock
DIY triangle thingies
DIY Ogee tarp pitched low over hammock, but not too close to the ground

Top:
1988 vintage kelty ridgeway 15* mummy bag on top as a TQ
single layer fleece TQ
small fleece blanket as a pillow

Bottom:
closest to hammock: Fleece DIY UQ (single layer fleece with nylon shell on both sides. KAQ dimensions and cut)
outside layer: 3 layer IX UQ with pleats instead of darts and 1.1oz RS shell on bottom only

Me:
knit cap
long sleeve single layer UnderArmor type shirt
"performance fleece" long pants
no gloves
I removed my fleece pullover and wool socks pretty quickly as I was too warm.

[Hokie Hanger]

I would think that the IX would be better on the outside. You don't have to worry about compressing 1 layer of fleece as much as 3 layers of IX. You also don't have to worry about moisture compromising the warmth of fleece as the IX is almost a vapor barrier.

Are you a warm or cold sleeper? How well to you think the IX underquilt will perform by itself?

[MacEntyre]

I would think that the IX would be better on the outside. ... You also don't have to worry about moisture compromising the warmth of fleece as the IX is almost a vapor barrier.
It works well on the outside, but you do have to worry about condensation in your insulation. You are the source of the moisture, not the outside air.

[Hokie Hanger]

I was just thinking that any moisture shouldn't affect the warmth of synthetic fleece. I wasn't trying to say which side the moisture was coming from.

:) I can rationalize either way. So, the next try will be with IX on the inside to see if there is a noticeable difference.

I tend to be a fairly cold sleeper. VERY sensitive to not having any air gaps.
No issues with air gaps with the first setup, and I suspect the inverse to be the same.
I'll add full details of my suspension system when I have time... hopefully this week.

For my first attempt at a project of this size and scope I’m happy with how it turned out. No close-up’s because it looks better from this distance. For all you Christian brothers and sisters out there I think Gross Grain is a lot like Grace --- It covers a multitude of sins:lol: I’m heading out on an eight mile circuit hike here tomorrow in St. Anthony’s Wilderness Pa, and hope to get some pictures of it set up. I’m sure if I make a bag for it I can get it packed down to a smaller size, hopefully the width of a two liter bottle and no more than 12 inches high. My finished weight with the triangles and biners is 17 oz.

Wow Gris. Looks awesome.
Are you sure that was your first big project? :cool:

I like the mid-adjustment cord lock configuration you used. Really lets you dial in the fit of the UQ on the hammock. I have mine adjusted so that my UQ is diagonal on my hammock to more closely match my diagonal lay... same concept as the HH asym tarp.
I've put paper clips through the loop of shock cord at each cord lock so that the shock cord loop can't pull back through the cord lock.

[sc_rupiper]

On my IX UQ i covered the outside face w/ a 1.9 oz ripstop and cut the ripstop 2 5/8" wider along the edges than the IX. This let me wrap the RS around the edges to form my channels. The only grossgrain I used was for small suspension loops at the four corners. Time will tell how well the RS channels hold up. Worst case if they start to wear I cut off the RS chanels and replace them with grossgrain then... I don't think that will happen though, 1.9 oz RS is pretty stout, but its what I had on hand (left overs!)

What I;ve done is sew a few small piece of grossgain to the RS at the shockcord exit before rolling over the channel. Then the shockcord rubs on the grossgain instead of the the RS. I do this on stuff sacks as well.

[Gris]

Here are the pictures of my first attempt at setting up the UQ. The hike we were supposed to go on got canceled because of snow and ice, so I went ahead and took the opportunity to pitch the hammock and fit the UQ while I was up in that region. I plan on using this UQ on my first section hike (Pa. 325 to Port Clinton) coming up in late March here on the AT in Pa. Hopefully before then I will get the hang of how to adjust it.

[scum]

Just wanted to report back on this again. Took this out again last weekend into low-mid teen temps and I was extremely cozy warm. I did make the change to attaching to my ridgeline using some prussik knots (similar attachment to using triangle thingies) which made a world of difference. That plus the added draft tubes made air gaps nearly impossible. I was able to go to my side and completely switch angles (feet hanging off to the right vs left) throughout the night and it required little more than a tug to ensure it was still wrapping my shoulders and legs properly.

Awesome, simple, effective design. Couldn't be happier. Thanks again for sharing scittlefield!

[sclittlefield]

Thanks so much for all the field reports guys - that's as or more useful than the instructions!

Mr. Littlefield,

I'm new so please forgive me if I have overlooked something. I like your DIY idea, tutorial and all. I am planning to make an UQ and will use them. My question is; I am 5'8". I was planning a 6' UQ. Could I just use IX 6' long to make mine? I am thinking my head and toes would then be covered. My first hammock just arrived in the mail but I think I shall have a bottom long enough for a 6' UQ. So what say you?

So what say you?

I'm not Scott, but I made one of these and also yearned for a longer UQ.
The 60" length of this design appears to be a result of the 60" wide roll of IX.
The way Scott laid this out allows very efficient use of the IX material so that a 3 layer UQ that covers the main heat producing areas of the body to be insulated with a minimum IX used.

I think you will be surprised how effective the less-than-full-coverage design is at keeping you warm. However, some folks use their sit pad or jacket under their feet to cover the area the UQ does not.

Seems to me that the only down side of making a bigger one is that it will be larger and heavier in your pack.

I'm experimenting with a much larger design and substituting 1/32" PE foam for IX. You can follow that thread to see how that works out (haven't field tested it yet) http://www.hammockforums.net/forum/showthread.php?t=30375

[rjcress]

Finally weighed my 3 layer IX UQ. I had guessed it would be around 16oz
The new scale said 454.7 grams or 16.03 oz, including the stuff sack (about 1 oz, suspension triangles, shock cord suspension, and several barrel locks in the suspension. Not bad.

[BodhiKnight]

I'm having cbs issues even after installing triangle things in my 3 layer. I don't get it. It's making my ocd flare up. Any help out there in hammock land¿?

A CBS cold spot is often from having that part of the UQ too tight to the hammock so that the IX layers are pressed together with no air gap between the layers. Fit I rather important with IX :)

[BodhiKnight]

I'll loosen it up a bit and see what happens. Thanks RJ

[BodhiKnight]

Its loose but sealed and cbs persists. How much gap between body and underquilt?

Agreed, I think this is right on the money. You may need to scrap the triangle thingies - it may be that they're wanting to pull up too much, instead of up and out. UQ's can take some serious tweaking to get set up just right, but once it's set, you should be good to go and not need to change anything unless you change hammocks.

[BodhiKnight]

Ill give that a shot. Thanks Scott.

+1 on losing the triangles. I made mine at the start w/ triangles then when test hanging I quickly realized they were not needed on my hammock for a good seal and actually made things worse for me. I just have the UQ bungies looped over the gathered ball at each end of the hammock and that works good for me.

[BodhiKnight]

Works much better without triangle thingies. Tinkering a bit more for a warmer fetal position. Thanks for the help.

[SpaceCadet]

Sorry if this question has been asked, this is a long thread and I didn't' read EVERY post.

For the shell, does it need to be breathable? Would it be ok for me to use coated ripstop? Does it matter at all?

[Astrolope]

Since were on the topic of questions that may already be asked. Any Hennessy sleepers how do you fit it for the asym lay? I'm a little confuzzled and this would be my first large project DIY...

Yes or no. Insultex is breathable, but only very slightly. If you use non-breathable shell material, I'd recommend you do either a non-breathable layer against the hammock and breathable away from the hammock, or non-breathable on both sides.

In most circumstances, it's not advisable to do breathable against hammock and non-breathable on the other side. Body moisture gets into the insulation but cannot escape out the other side. Insultex is more forgiving in this area though - because it doesn't trap moisture the way down or climashield does - it's more hydrophobic.


Since were on the topic of questions that may already be asked. Any Hennessy sleepers how do you fit it for the asym lay? I'm a little confuzzled and this would be my first large project DIY...

I sleep asymmetrically in my hammock with this underquilt w/o problems. If you want, what would be useful would be to make loops at the edge corresponding to your tie-outs, and run the tie-out through the loop. That would keep the underquilt in place very well.

[lustreking]

I have two questions about making one of these.

I think that I'd like to make a two layer version, so it's less bulky in warmer weather. Can I just make it with the bottom and middle layer, and then make the top layer separate and just place it on top of the other two when more warmth is needed? Or should I have some kind of buttons, or velcro to attach them to maintain the spacing?

I'm also planning on just putting the shell material on the outside. Would there be any issues with tacking the shell nylon to the bottom IX layer, and then doing the pleating as one whole piece?

I decided to go for it, and this method turned out great.

I decided make a two layer with the optional top layer, and put grosgrain tabs on the corners like the Molly Mac IX underquilts appear to have. When I want both layers, I'll just clip them together with the really tiny (#0?) s-biners, and attach the suspension lines to those.

My question: On the two layer version, I rolled the nylon cover over the top side to cover the edges of the insultex (as well as to create a drawstring channel). On the top layer, I didn't think ahead far enough to make this layer a little larger to allow for a rolled hem. What should I do to finish the edges of the top layer? I was thinking maybe bias tape, that should be pretty light weight, right?

Yeah, bias tape would be light, and work well. You can make your own if you want, with some scrap ripstop. Just cut 2" (or whatever width seems right) strips at an angle (the bias), and sew the strips together for a long length of bias tape. Pre-made is less of a hassle, but it's not terribly hard to make your own. You can get bias tape makers (they help make the double fold part really easy) on Ebay for cheap.

In fact, you don't even need it to be bias tape. You can just cut straight strips of your scrap ripstop shell material and do the same thing. Bias tape is helpful on things with major curves. On something like this, it's not necessary that it be cut on the bias.

Yeah, I was thinking about using the bias tape because it was already folded, however, the bias tape at JoAnn's was 40% cotton, so I decided against it. I bought a roll of 7/8" polyester ribbon. I'll try folding that in half and pressing it before I sew it on.

Thanks for the plans! I can't wait to try it out the weekend.

[mwm]

Great read, but I am wondering would this be warmer than a DIY sleeping bag UQ??? I'm still a noob, and I'm trying to decide which way to go. Thks.

[sclittlefield]

Great read, but I am wondering would this be warmer than a DIY sleeping bag UQ??? I'm still a noob, and I'm trying to decide which way to go. Thks.

That would depend entirely on the quality and type of the sleeping bag you're going to use. The IX underquilt is just one way to accomplish the goal, and there are lots of right ways to do it.

Using these instructions will be much less expensive than buying a quality sleeping bag, but if you've already got one that's available for cutting up, go for it! They can work great. Do a search here and you'll find quite a few posts from folks who've done just that and have some instructions on how do go about it. You can even design it such that the sleeping bag is still fully usable as a sleeping bag when not used as an underquilt.

Enjoy whatever DIY project you choose! :)

[inabag]

Ordered everything to make a 2 layer IX UQ, with an optional 3rd layer insert yesterday. Looking forward to putting this project together. I have a 5 day trip planned the first week in Sept, so it will get a nice test then.

[Born_Old]

I want to make a 2 layer version using this template. Should I go for the bottom/middle, middle/top, or does the template not work for 2 layers.

I have 3 yards so I was thinking of doing the bottom-middle so I could add the top layer if needed. If someone has done something like this I would love to know how it worked for you. More specific if the IX was too far from the hammock and made the nights chilly.

[secondechomatt]

found the insultex, gonna order this week!

[Fronkey]

I am having a difficult time locating insultex. I've looked on backwoods and t2t and can't seem to find the insultex by the yard.

help?

Just finished my 3 layer IX UQ and will be testing it tonight...I tried it out on a breezy 60F temp and it was really warm.

I made it to the plans specs and it 16 oz, I was going to make a stuff sack for it but decided to just stuff it into my backpack since it is so light and easy roll up.

I will update yawl after a 50 degree nights sleep.

thank you! I edited quickly, hoping no one saw my error in plain vision! :lol:

[vinnya42]

Did my first sleep test with my 3 layer IX, it was a good sleep and plenty warm for a low of 50 degrees F. I followed the original directions exactly and am very happy. The back of my legs and feet got a little cold but nothing that kept me awake. VERY happy with the plans and my new IX UQ!

One question: What do you where when sleeping with your UQ in weather under 50 degrees? I was in shorts and T shirt and hat and fleese socks...do yawl use more than that when it gets colder or do you beef up you UQ instead?

[Otter1]

Vinny,

I wear long johns below 50 (usually). I'll always have a puffy jacket handy for temps 40 or below. May not need it for sleep, but I have it for around camp anyway, so it's no weight penalty.

Glad you new UQ worked well. Do you think your leg/feet coldness can be improved by adjusting the suspension, or is it caused by the IX/design itself?

[vinnya42]

Funny Money I think the cold was from the head of my hammock too high and me sliding down past my UQ and until the UQ was right at my butt...instead of my mid thigh. Next time I will get the hammock set right. I could also wear long johns and zip my sleeping back up to my butt making my sleeping bag have a leg box instead of a foot box.

[jeepthangjim]

Well. I just placed my order with BWDD yesterday. I tossed around several UQ options and finally decided on this one due to economy and efficiency. I live in MS so the winters here don't usually get super cold. I figure between this UQ, my pad, sleeping bag, and clothing options I should be able mix and match to handle anything this region can throw at me. Now I just need to get a sewing machine.

:confused: I have a question about using a space blanket in between the hammock and the UQ though. Will the use of a space blanket reflect any of the heat back into the hammock preventing it from warming up the UQ efficiently?

Thanks so much guys!

[jima59]

How do you end up hanging this uq? I understand the channels but is the long one tied together or how do you get it over the end knots if its tied together?

[JohnSawyer]

:confused: I have a question about using a space blanket in between the hammock and the UQ though. Will the use of a space blanket reflect any of the heat back into the hammock preventing it from warming up the UQ efficiently?


The space blanket when used that way really acts like a vapor barrier. The reflective qualities help, but a lost of heat is passed through by conduction, since it's against your back. I've used a SB inside an UQ to extend the temps... it helped...


How do you end up hanging this uq? I understand the channels but is the long one tied together or how do you get it over the end knots if its tied together?


SOme just loop the shock cord over the whipped bundle, others use micro-biners to clip it to the suspension at the end. "Triangle thingies" are also used by some...

[enoorange]

Here is the first time using my DIY UQ per OP sclittlefield (and first time sleeping in hammock as a matter of fact).
I bought the materials, did the cutting and wife sewed. Green Ripstop top/bottom, 3 layers IX inside , camouflage gross grain, sock cord all around and a cord stop at each corner.
LOVE IT!! Temperatures were warmer than expected but it did get to 45F one night. <$50 total cost...right under 16 oz total weight.
Not sure if I hung it right but it worked well and it's a keeper! 5'9" tall and usually slept on my side kinda curled up just a bit.

Thanks for the instructions sclittlefield !!:D

On the top side I used a Kelty light 40F down bag unzipped with feet in pocket and rest laying on top.

[vinnya42]

Looks Awesome...Great Job!!

[lustreking]

I haven't been able to get out much this year, but I finally got camp and use my 3-layer underquilt for the second time. It got to a low of 43ºF, and I stayed nice and warm.

For the cost, ease of construction, weight, and low bulk, this IX underquilt can't be beat.

[jasco]

I have been browsing around these forums for many months now and finally decided to post something here since I am researching making an UQ for my Hennessy expedition asym.

I love this design and I really like the idea of using IX for the installation. But I have one concern regarding the bottom entry used on Hennessy hammocks. I have read every post on this thread and don't remember seeing any information on bottom entry. Also, I don't really want to mod my hammock to make it top entry because I really do like the bottom entry.

Will the bottom entry cause a problem with design? For example, will the UQ cover the "door" and making getting in and out impossible...

I guess this is more of a general question for UQs and bottom entry hammocks.

Thanks!

P.S. Thank you so much for all the design ideas!

[sclittlefield]

Hey Jasco,
No, it won't make it impossible to get out, but it's certainly something to keep in mind. The shock cord system allows you to move the quilt around quite a bit, so you can push it back out of the way, slip in, and let it snap back. You might find you need to reach out through the hammock entry to adjust a little bit - having it right where you need it ahead of time is going to go a long way here, as you can't reach out the side to adjust.

I'd recommend putting loops in your quilt, corresponding to the two tie-outs on your Hennessy hammock - run the hammock tie-outs through those loops when you stake them out. This will keep the quilt right about where it needs to be all the time.

Enjoy your projects!

- Scott

[jasco]

Scott,

Thanks for the quick reply. I think I am going to take the KAQ design (http://www.hammockforums.net/index.php?page=kaq) and adopt it for IX insulation...then throw a few mods, such as a removable top layer of IX and maybe tweak the suspension on the foot end to make getting in and out a bit easier.

Once I get them done, I'll post the plans for the IX since the darts will need to be modified a little for the asym design.

I just finished my IX UQ today. It was a fun project. Thank you so much for the write up. I can't wait to try it out. :D

Does anyone have any sources for the Insultex other than those listed at the beginning of this thread? DIY Gear Supply is out and the other source doesn't show it on their website.

I've done the Google search and come up blank.

I don't know any sources but you could contact DIY Gear Supply and ask him when he's getting some more.

It's on order and should be back in stock this next week. The only other place I am aware of that sells IX is Tree to Tree Trail Gear. I didn't see it on their site either, might want to toss them a note to see if it will still be retailed.

[Lost_Biker]

Just finished my IX Underquilt today using rjcress's excellent instructions at his gear review site. Ordered all the materials from DIY Gear Supply and although it took 3 days of off and on work and fiddling around trying to decide exactly what I wanted (or needed), I'm quite pleased with it. Tonight is going to dip into the 30's, so I will be out getting the hang of using an underquilt for the first time. I'm moving up from pads and big sleeping bags.
I had an old 40 degree Wiggy's sleeping bag that finally wore out after 15 years, so I took it apart to reuse the Lamilite insulation in the draft tubes I put in the underquilt. They're 3 inch tubes all the way around. Snugs up real nice with no gaps that I can see or feel. I used pleats instead of darts (6 inches long) on the insultex and got a good bowl shape. This was my first "big" project - lots of mistakes but a lot learned about thread injection.
Now the family can have the living room back. For awhile it looked like a fabric store blew up.
Next project starting tomorrow is a hammock sock! Was told to take it out to the shed this time.:confused:

[Timmer]

The replacement stock is due in this week! I'm getting eager to start doing some serious thread injecting.

[n1ck0l3man]

I am horrible at sewing and I want to make an IX UQ as cheap and easily as possible. I sleep very cold. With that in mind I was thinking about buying a 2Q2Z Silnylon UQP and then inserting 3 to 4 layers of IX that has been velcro-ed together in such a manner that their would ample air space in between each sheet. Has anyone tried this? I am a new hanger and a new DIY. I figured this would make it more adjustable between seasons and easier to experiment with. Any advice? Your quilts look great guys!

if you plan on using the underquilt protector to hold up the IX UQ my guess would be no

if you can find a way to hang it on it's own i don't see why it wouldn't work
but it would need to be sewn to a point ... might get away without but not sure how

[cwford]

So I finally finished my IX uq. I don't think I deviated much if at all from the directions on this thread. I have 3 layers of IX and an outer layer of 1.1 camo ripstop. However I'm curious as to what the "loft" on this thing should be. Mine seems really thin -- about 1/4" (maybe a bit more). Does this seem correct?

I haven't had a chance to test it yet so all could be just fine. Its not really cold enough here in TX yet anyway to tell if its working well or not.

Loft is a by-product of down ..
what you are talking about is "air gaps" in between the layers ;)

from what i take of it the air gaps are not going to be very big you will not tell unless it is hanging on a hammock since IX does not Loft like Down will
hang it on your hammock and you should tell then if there are air space in between the layers ;)

I'm not sure what it needs to be to work well, but mine is more like 1-1.5" or more with three layers. That's in the center, not the perimeter, of course.

[G.L.P.]

is that total or just in between each layer ?

i just ordered some IX from you today .... i'm going to make a 2 layer with a ripstop outer shell as my new summer UQ for temps 50F and above

[cwford]

I realize its not technically "loft" in the same way that down or synthetic fill has loft. But in the sense of space between the inner layer and outer layer its the same thing. Maybe I should have used the term "dead air space".

I have hung the UQ in the house and there's nowhere near 1 - 1.5 inches of dead air space between the top and the bottom layers. Given that each layer is 42 inches wide after the darts are made, how is it possible to have that large of a difference? I understand that the darts turn the 2D shape into a 3D shape. It seems to me that if the final width is the same for all 3 then the shape is essentially the same for all 3. This would cause there to be little to no dead air space.

Where am I going wrong here?

[Jazilla]

The dart in each layer makes like a scoop or cupped shape in the IX stopping it from laying completely flat. If the darts are staggered like Scott shows then the cupped shapes keep space between the layers. This should give the dead air space needed.

Now this is all in theory. I haven't made one for myself so I have no real clue.

[tatersalad66]

just order the makings for mine today, looking forward to trying it!

[Timmer]

My UQ materials arrived today. Time to start sewing!

[Timmer]

I finished my underquilt using the plans in this thread. I used 3 layers of Insultex. It was my first thread injector project (not counting hemming up a couple pairs of pants) using my Viking Husqvarna sewing machine that I purchased from a garage sale. It took about 4 hours to sew up. The hardest part was threading the shock cord.

Here's the finished product:

http://timmer.smugmug.com/Hobbies/Sewing-Projects/i-Dwg6wbv/0/M/2492-M.jpg

I used camo ripstop on the top and bottom and ironed the folded over Gross Grain to aid in stitching them to the underquilt.

While I was at it, I made a little stuff sack and it came out pretty nice.

http://timmer.smugmug.com/Hobbies/Sewing-Projects/i-C9V9Prm/0/M/2494-M.jpg

The overall weight in the sack is 18.45 ounces which is quite acceptable for me.

Thanks to SCLittlefield for posting the plans and providing the encouragement to take on this project.

[Holger]

Any ideas where I can get IX in Australia?

[All Kinds]

DISCLAIMER: I have never used an UQ. I have also never backpacked (yet). My DIY experience is one gathered end hammock ala Knotty's instructions.

Would it be worthwhile to have more layers of IX? I see that having 3 layers can get you into the 30's if everything is set right. Has anybody tried 5 layers?

My plan is to build the base 3 layer with draft tubes like Scum did, but with small draft tubes running the long way as well. Then build a completely separate 2 layer slightly smaller so that it nests inside the larger.

So essentially when used together, [starting on the outside] I would have ripstop, 3 layers of IX, ripstop, ripstop, 2 layers of IX, ripstop.

Ideally I could use both individually in warmer weather, and combined down to ??? deg in cold.

My concern is that there is a point of diminishing returns and adding all the weight wouldn't give back much in warmth. Also does having all the layers of ripstop cause issues?

I haven't quite figured it out yet, but I am thinking some sort of quick disconnect for the suspension on the 2 layer so it is out of the way when used in system.

Does this have merit? I may be out in left field on this! :confused:
Thanks for any feedback.

[BodhiKnight]

I have 2 IX 3 layer UQs both built the same as the OP but with head and foot end draft tubes. I put one one top of the other, bottom UQ hung looser than the top UQ.

Works great for the back yard. Got down to 28f last night with a feels like 22f I was warm and toasty.

Too bulky for the trail. You can make a climashield or primaloft UQ and velcro it on to the top of the 3 layer IX. Or sew it in with one line of stitching and seam rip it off when the weather breaks.

How low temp are you trying to go?

I don't have a specific temp goal in mind, but I want to be able to do winter camping. Until the last couple of weeks I had never been out below 50. Using a walmart blue pad I was comfortable in the hammock at 38 Thurs night.

It's now a personal challenge to see how low I can go. (without down - allergies)

Thanks for the feedback, some of the other insulators may be on the horizon, but for now I want to stick to IX. I will probably order the materials tonight. I am going to need two anyway in the spring, cause I want to take my son out with me.

2 layers of ripstop isnt going to add much weight. Diminishing returns? 2 extra layers of IX is added warmth, no diminishing returns here.

Make your suspension the same for both UQs same lengths. Tie a knot in one of the prussics (so you have two loops, pass through the top for your top UQ and the bottom for the bottom UQ.

[Moradiss]

Would using 1/4" polyester batting between layers of IQ work for creating an airspace between the layers? Not sure of weight, but I would think you could cut the batting into strips, go around the perimeter of the IQ, and strips across the IQ, spaced far enough apart to keep the IQ layers from touching.

With a differential cut and hanging it properly the batting in between is unnecessary.

Besides, Polyester batting would be too heavy/bulky.

Hello,

I'm thinking of giving this a shot, and think I'm going to order from http://www.diygearsupply.com. On their site the Nylon is listed as either Calendared or Uncalendared. Will the Uncalendared Nylon work for an IX UQ?

Thanks,

KC

[BodhiKnight]

Yes it will. Have fun on you IX adventure.

[Netmonster]

Is is better to have a shell (nylon) on the side that butts up against the hammocks bottom or can it just be the IX material?

KC

[BodhiKnight]

Shell on outside. IX next to butt.

[Boulderman]

Here's a question: I use a JRB Bridge hammock with a large NeoAir pad. Would a 2-3 layer IX quilt appreciably increase the warmth of my setup? I don't know how an air pad operates with insulation hung under it. I think it would work, but does anyone have experience with this?

[Jazilla]

Yes it would work. More insulation = warmer butt.

just made a 2 layer with a ripstop outside shell tonight.... came out nice
11oz i tried it out and had a little CBS but other than that it worked out good
the temp was 50F
should make a good summer UQ i might open it up and drop in a oz of down to take care of the cbs

I'd love to hear how that works out if you go for it. With no baffles, the down should just settle to the cbs area anyway, and as long as the differential cut keeps the layers separated, that might be a neat solution to boost this little rig.

yeah that was my hope too... that it will settle down to the bottom
i think it will fix the CBS ... i mean it wasn't bad ... i could have put my sit pad under my butt and be fine all night in the 40's my upper body was nice and warm just my butt i also thing the way i'm hanging it has to do with it... i think ti's too tight against the hammock i might put tabs on it and set it up for my WBBB since that is the hammock i will use it with
but i will report back how it works out... i need to order some down anyway
as far as my Diff. cut i think it's good i put my hands under me and it feels like i have a good 1-1.5 of an air gap in there
didn't take long to make and was VERY easy... it's a great first UQ project for someone just starting out and it works i think with the 3rd layer i could take it to 35F easy ... but mine is for summer and will never see those temps

i'll post some pics later tonight after i'm done editing this video from the last hang :rolleyes:

[BodhiKnight]

just made a 2 layer with a ripstop outside shell tonight.... came out nice
11oz i tried it out and had a little CBS but other than that it worked out good
the temp was 50F
should make a good summer UQ i might open it up and drop in a oz of down to take care of the cbs

Down wont do much of anything if you load up at the cbs area if you dont stop the air gap at the foot end. The head end seals nicely with no modification, but the foot? Nopes.

In my experience the cbs is caused by the crease in the under knee area that makes a gap for heat to flow out and wind to flow in. A draft tube fixes this, see Scums draft tubes. http://www.hammockforums.net/forum/showthread.php?t=41139

It helped me get 10 extra degrees lower out of a 3 layer IX.

Hope it works.

Do you think the down will stay sufficiently distributed without baffles? I have an old down vest and I'm contemplating this as well...

My CBS is not from air gaps.... i'm aware of the air gap problem ;).... mine was that it's only a 2 layer UQ so being it was in the high 40's i was already pushing it's limits ... that and cause of medical problems my lower back is always cold ... i know the air gaps were closed my legs were warm and my back just my butt was cool (cold might have been the wrong word)
the goal of the extra oz of down is to see how far i can take the 2 layer ver of this quilt and for added warmth for my lower back area ...
overall as is i could have slept fine ... but feel i can get a little more out of it with the down added in


as for the other question from Boulderman
i hope so ... it's not a big air space so an oz should be fine and it should all fall to the lowest point in the UQ so it should collect where i need it...;)
at least it should :rolleyes: i guess i will find out HAHAHA

I made an under quilt using a combination of these plans for the hammock and tarp I made this fall using instructions here.
The local rental place moves lots of TVs this time of year and they saved the insulation for me. Most of the sheets were long and wide enough. I used packing tape to piece together those that weren't.
It's a 70-inch x 42-inch 3-layer UQ with ripstop from Joann's on top and bottom. It rolls up as small as the others in this thread and works great. It weighs 16 ounces with the shock cord.
I've used it for a nap, but not overnight yet. It's very warm. I'll get a picture soon of all three.
Thanks for the help!

I made a 3 layer one for my 6'4" husband and had to increase all the length measurements by about a foot. I also ended up guess-ta-mating on the darts too. I didn't write anything down as I did each layer one at a time. I figured that as long as I had the length and width for the first layer the way I wanted it, that the next two layers just needed to be a bit smaller (with the 3rd layer the smallest). That way the air gap between each layer was maintained.

Good luck.

[Kodiak1]

Hi, Can anyone help me? I am making the under quilt and I am 6'5". So I would like to make my UQ 7 ft in length. Is it necessary for me to keep the 48in width or can I leave the IX 60 inch width? I am tall and slim. Thanks for any help.

[Kodiak1]

Hi did you keep the with at 48 in

Keep the width to 48". I'm 6'1" and skinny. Many user more narrow UQ's but I toss 'n turn so the extra width is nice. Please show us your results!

[canoebie]

I left mine at 60 and my wife loves it because it wraps around her no matter how she tosses and turns. We mostly canoe so the extra bulk is a non issue. There are some advantages to the extra witdth. Leaves room for error in suspending.

[jago0020]

I do most of my hanging in 40-60 degrees (which is pretty consistent in MN from June-September). Would it be possible to make a two-layer IX with a nylon outside that is connected to the hammock? I am new to the UQ idea (trust my foam pad)- so I am assuming there is a reason this doesn't work as all of the UQs I have seen are designed to be removed. Just wondering if this is possible...

[Kodiak1]

Well I (with my a lot of help from wife) finished my underquilt.Thanks to sclittlfield for pattern and others of you who helped clarify things for us. We made mine 50" X 7' Tried it out last night my bottom stayed warm. As a newbie It was a learning experience I need a better top quilt or sleeping bag it got down to 12 degrees and I was starting to get cold after 5 hrs so when I got up to relieve myself I called it quits. I'll keep trying to improve Thanks everybody for your input.

[Otter1]

Wow Kodiak! I am impressed how low (temp) you achieved!!!! Even though you got cold that's impressive.

Did you stick w/3 layers? What is the weight? Great work 0 it looks nice and obviously performs.

[Kodiak1]

Yes funny money we stayed with 3 layer also had some foam wrap that I brought home from work that I laid on the bottom of my hammock. as far as weight goes I am not sure. Plan on using the UQ more in the colder weather so if there is snow on the ground I'll pull it in my pulk if I figure out the weight I;ll let you know.

[scum]

Just wanted to report back on this. Took my UQ down to 8 degrees and was very comfy. I added a very thin/cheap (little more than a couple layers of an emergency blanket)windshield screen between the uq and hammock. Also had a cut down torso size Walmart Blue pad (Waffle pattern style) directly under me. I was very comfy and warm. Only condensation issues I had were from my breath on my overcover. Couldn't be happier with this thing.

[actuallyarobot]

I am making an UQ for my son and have never actually seen one myself. When running the shock cord through the long sides, do you also run through one of the short ends to get from one long channel to other?

No, the shock cord for suspension of the quilt only goes through the long sides, there will be separate lengths of shock cord in the end to "cinch" the quilt up on the gathered ends of the hammock. Clear as mud right? Here is an illustrated guide for this IX quilt that helped me.

Many many thanks!!!!

Very nice directions thanks.

Anybody have thoughts on creating a permanent UQ instead of a removable? I have a HH Exped Asym and think that if I sew a full size layer (like the pockets on a Clark) on the bottom, using the template/instructions here I could make a permanent UQ. Or even set it up so the IX can be removed for warm weather.

That's an interesting idea. You would definitely get a great seal going that route, no fiddle factor on the underquilt suspension. Let us know if you do it.
