ok i'm wondering about this whole quilt thing.i have been pricing winter bags and am wondering if a s/s is enough to just quilt it.i have a overly talented sewer of a wife and if a quilt is possible for really cold nights then making one is the way to go for me -last year i was in a inadequate bag so this year i'm gonna change things up but unsure if a quilt is sufficient for say -10 to -20 c thx
-20 C = -4 F if my math is correct. The only underquilt capable of taking you that low I'm aware of is the Mt. Washington 4-season by JRB. Near or below zero F (about -18 C) most folks are using pads. I've had good luck with the Speer Segmented Pad Extender from Speer hammocks with a thermarest.

I have used the Winter Yeti alone down to 10*F and added a 3/8" pad under my butt at 4*F (precautionary). still inside the comfort zone
Shug used a blue ccf, BA insulated pad and a full UQ at -26*F here
Cannibal has used his Winter Yeti below 0*F stand alone, I believe.
I would think of doubling up UQs at seriously low temps...pads included to supplement
While the Super Shelter was augmented for 1 night down to -26* F I would be loath to try and do that for any length of time. The Mt. Washington is reportedly good to those kinds of temps But I would think combining a lighter underquilt with the super shelter (if you already have one) would be a very feasible option. I have been down to ~12*F with my super shelter and a cheap-o 0* sleeping bag. It can be done.
There is a Canadian here ( in Nova Scotia? sp?) who has used a SS, by itself :scared: at well below 0F. Who was that, ToddKMiller? Any one remember? Any way, he might be a good one to consult. And of course KWPapke used a well augmented one to minus 26F.Quote:

It probably wouldn't take a whole bunch to push a JRB MWUQ or WB winter Yeti to the temps you are mentioning, but you probably would need a little something extra. Of course, depending greatly on your cold tolerance.
Turk would be another one well able to advise you, if you can find him. PM him.
thx guys my research will continue.-last year i was down to -15sh with just the s/s and -7c bag and was not toasty but i never died either,that said,i'm not going to do that again as i will be alot farther north on some trips this winter where it can get a whole lot colder.i think the s/s with space blanket works well enough on it's own but maybe i will still need the bottom of a bag to trap more heat in.the real problem for me then is to tell my wife and 5kids that daddy needs 400+ bucks for a good sleeping bag to sleep outside a few nights this winter-hard to justify for a poor man:D
I augmented my HH SS with a thicker full size open cell pad cut from a Wally World egg crate foam twin sized bed topper, and a 1/2 size underquilt (butt to shoulders coverage) made from a doubled up poncho liner. It took me to warmer than comfortable up in Oswegatchie earlier this month (night time temps unknown, but I woke with a layer of cracking ice from the condensation on the inside of the tarp). I'll be trying the same set up for the 2010 winter trip to the Adirondacks.
Positives:The foam topper cost me about 12 bucks and fills the Under Cover edge to edge and nearly end to end. I simply stuck it in and then put my loaded pack in to weight the hammock and then trimmed and darted the pad until it fit (maybe 5 minutes total work with some EMT shears).
On the negative: it is incredible bulky, requiring an MSS 9 strap compression sack to get it down to a travel size, and I have no idea on the weight but probably around 1.5 pounds.

I spent half that for my synthetic 0F REI bag. Yes, despite the common wisdom, having a bag beneath you makes a HUGE difference, especially with synth fill.Quote:

You used that special ( name?) thin pad in the UC, right? Do you think that weighted the UC enough to cause enough sag to prevent the UC elastic tension from compressing the down parka or bag? Thus allowing it to loft up fully underneath you, and just enough to contact your back?Quote:

Also, compression of the (especially with down) loft by the SSUC elastics definitely compresses loft at least some what. But it would seem you pretty much get full warmth out of the parkas you place in the UC, considering your temps. Which got me to wondering if the pad's weight might have helped counter that tension a bit or a lot? Any theories?
