I bought this bag due to being claustrophobic in a conventional mummy bag. Having my arms free, and legs as well with the foot drawstring released is so free and convienient, that I wonder why more products like this aren't made. My bag has been on three trips so far with temps in the low thirties on the coldest night, and provided enough warmth. Mid night pee breaks are so easy without getting cold. Just wear the bag like a jacket and go for it. It can be worn for cooking or lounging as well. The cost is dear, but for a claustrophobe like me there is no lightweight alternative. I had Patch handwarmer pockets, full length zipper and overstuff added to the standard bag, which added extra cost. It took about 90 days to get, and came in a cardboard box with no storage sack for over seven hundred bones! I'm sure glad I like the bag! I'll update the review when I get more trips on it.

Previous bag: Marmot Gortex 0 degree. Nice dry toasty bag, but not for claustrophobes. I used it as a quilt so I wouldn't freak out.
