    IX UQ Shifting Issues

    Hey all,
    I recently made a 3/4 length IX underquilt, and I'm having trouble keeping it in place while sleeping/tossing and turning. I am using it in the Warbonnet Blackbird. I don't have time to test it out again before a big trip, so I need to modify it blind.

    The UQ is a basic rectangle with a couple pleats on the short ends. It's three layers of IX with a nylon layer on the outside. I have channels on all four sides, but there's nothing in them yet. I sewed on six grosgrain loops: one on each corner, and one in the center of each short side.

    I used it over the weekend by attaching it to the hammock with shock cord and micro-biners on all four corners.
    It seemed to be working fine, but I'm a side sleeper, and each time I would switch sides, the UQ would slide away from the left/door side of the WBBB. I could open up the zipper and pull it up, but it wouldn't stay there for long. I also got a cold spot near my neck where I think the top short edge was gaping. The coldest temp of the night was around freezing (32 degrees).

    Any advice about what I could add to keep it in place?
    Would running shock cord through the channels on the long sides do it?
    Should I use one long piece of shock cord through the long sides that doubles as the suspension?
    Any thoughts are appreciated.

    I have the same trouble with every UQ. I may be a restless sleeper. What I do is sew small 1/4" elastic loops on teh hammock where I want the 4 corners of the UQ to be. I either use a mitten clip but usually just use the same biner that holds the UQ. Also AHE has those triangle thingies that hold an UQ in place better. I never tried one but I bet it would work.

    Fantastic results! If you were acceptably comfortable at freezing with a poorly fitting 3 layer IX UQ, you done real good!

    From the picture, it appears that you have brought the suspension together up at the ridgeline, so the end gaps will go away when someone is in the hammock. That's a good rig.

    Tighten the suspension.

    Try putting a shock cord in that end channel, and tightening it up. Also, you can bring the legs of the suspension together at the head end, like you did at the foot end. (Hard to tell which end is brought together above your top cover.)

    It might help... give it a try!

    That will make it easier to adjust it while you are inside. IMHO, you just need to tighten the suspension.

    Did you use a differential cut?

    P.S. The triangle thingies Dutch mentioned help do what you did when you brought the suspension legs together at the ridgeline.

    Wow! Thanks for all the feedback already. I will definitely bring along the supplies to try out some of these techniques next week.
    I hadn't considered modifying the actual hammock at all, as Dutch suggested, and that's a great idea.
    MacEntyre, I only tied up the suspension around the head, and I didn't tighten the suspension at all once it was on initially, so that's a quick fix I will definitely try.
    Thanks!

    Yes, at this stage of your experiment running a shock cord thru all of your channels will give you a full range of adjustments.
    You can try various adjustments on your trip.
    Then perhaps make them permanent later.

    Both of our experimental IX UQs now have four channels.
    One UQ from the beginning. Second as adjustment to figure were and how deep to adjust the darts.

    Having one long shockcord with cordlocks on 2 diagonal corners will give you a range of adjustment.
    ( or 4 corners for more range of adjustment ).

    I agree with MacEntyre, you have done well.

    Then all you need to do, IMHO, is put a shock cord in the head end channel and tighten it a bit, then tighten the suspension at the foot end. Oh, and get triangle thingies from AHE.

    The reason for tightening the suspension at the foot end is so you won't move the UQ up. You want your shoulders to be on the edge of the head end, to spread it and close the gaps.

    The reason you need to use the head end channel is because you did not put in enough darts. (Kinda what G...Hawk said...) I use four (4) darts, each 1.5" wide at the edge, in each end including the corners. No biggie, though, since you have a channel.

    Good luck!

    Sprite,

    I've been field testing a Baby Orca with a WBBB for a few months now and love it, but I noted the same issue. I've got 20 nights camping with it and more than 20 nights in the back yard. Low temp so far only 37F; still looking for the minimum, but getting close.

    On an outing I became frustrated and improvised this: cut up some para cord into two 12" lengths (one for each end). Hang the UQ shock cord suspension in the usual fashion around the knobby gathered ends. Follow the ridgeline in from each end about 14", then pull up the elastic suspension cord from each side. Attach the short paracord to the elastic cord at that point using a Prussic knot. Then take the two ends (now 6" long) and wrap them a few turns around the other elastic cord, draping it over the ridgeline. Secure with a shoelace knot. You can slide it to fine tune the underquilt hang. This acts like suspenders for the elastic line, bringing the corners up. You release the shoe knot and can leave the short cord attached when you take it down. It was a temporary fix, but I've not changed it yet.
