I have wanted a light UQ but wanted couldn't decide if I wanted to use down or synthetic. I remembered seeing the JCP down jacket UQ threads when I cam across a closeout at Costco. Two XXL vests for $12 each and about $5 in misc cordage and grosgrain later and I have my latest DIY solution. It took about 3hrs to disassemble the vests but I could do it in half the time now that I am more comfortable with a seam ripper. About 2 1/2 hrs to put it all back together.
I used a couple of the pockets for the stuff-sack. The grosgrain was a little stiff because of the print so I would not use printed again. The neck part of the vest are used as draft stops.
Total weight is 15.73oz. This should be good for me down to 45° or at least to take the chill off. I have tested it at 53° and I still feel the warmth.
Not sure how to add a description under the pictures but in order they are:
1. Purchased Vests, one deconstructed and 2 new. (green vests are for my son's UQ)
2. Layout for best fit.
3. Sewn together.
4. Add grosgrain around outside.
5. Run shock cord through ends and side channels.
6. Test hang. (Cord is a little loose, I shortened it for actual use)
7. Weighs in at 15.75oz including stuff-sack.
8. Finished in sack.
