It probably just slipped off during the night. That particular UQ was very much a prototype and there were some weaknesses compared with the final production model. Most notably being that it didn't 'cup' the shoulder the way the down Yetis do; hence the slippage.
I'd have to weigh it, or find the old thread. Honestly, I think that thread is one of the ones I deleted when I had a fit of anger at some point shortly after I got home from the AT (it's a bugger of a transition back to the "real world"). However, I really want to say that quilt was right at a pound (16oz). I'll throw it on the scale tonight to be sure.
I realize this is an AHE thread too and tried to focus more on the material than the construction. I do think the XP was very close to down in terms of insulation. At the same time, I have a theory on why the top quilts made from the same material aren't getting the same results. As we all know, CBS generally comes from gaps between the hammock and the quilt. The Yetis, as well as the KAQ I have, both seal-up extremely nice to the hammock. I can only assume Paul's continuation of the KAQs function and fit nearly, or better than the originals cause Paul's work does not suck! But a top quilt? They don't really seal, they just drape and synthetics don't drape half as well as down quilts IMO. *I think*, that synthetic insulation works great when it's against, or very nearly, your skin. It traps the heat quickly in that situation. When draped and pockets of air form, I believe it isn't nearly as efficient. Made more exaggerated by a sleeper that tends to roll around....like a groundling. :rolleyes: While I am still a semi-fan of synthetic insulation in underquilts, I am pretty exclusively a down-guy for my top quilts. I have a couple of synthetic top quilts, but they are strictly loaners. I don't think a synthetic top quilt, gram for gram, can take on a down top quilt.
And yes, for a top quilt in that picture I was using a very old synthetic bag. If memory serves, it was a Coleman bag. It was either a 0° or 15° bag. Plus a base shirt, plus a cotton shirt, plus a fleece pullover, plus a hoodie, plus...you get the idea. :D
