    by fromShivered to death Went camping in Ojai. Slept in tent with rain fly up with another person. Temp was mid 40s at night. I shivered my butt off. Was wearing long sleeve shirt and pants eventually put on a sweatshirt and got a small blanket to wrap my legs in. Finally fell asleep. Zipper also snagged a little. Which I would have been fine with had I been warm.

    by fromKelty did it again! Great bag! This bag kept me nice and warm in the Wallowas in September and I plan to use it often. The zipper does snag, so open and close carefully, but it fits me and keeps me comfortable.

    by fromgreat bag! I'm a very tall woman and was worried the bag might be too slim or too short. But this bag is very comfortable. I can sleep on my side very comfortably. I move a lot and the sleeping bag stayed zippered all night and didn't get twisted. This bag is ridiculously warm! I'm excited to go test in out in cold wyoming nights :)

    by fromSimply an excellent sleeping bag I bought three of these. One for myself and one for each of my two teenage boys. This is simply an excellent sleeping bag! We use it mainly for canoeing and camping and I really like the relatively compact size and low weight (for the price) and it's ability to keep you at a decent temperature over a wide temperature range. My boys even use it un-zipped at indoor sleep-overs. There are some reports of the zipper snagging easily. I find this untrue and we have no problems with snagging at all. It has some nifty little features that we actually use: The ability to be un-zipped from the bottom (actually a little ways up from the bottom) to stick a foot out when it gets too hot, the loops for hanging it up for drying and airing out and the string for tightening the hood. I am really happy with this bag.

    by fromGreat Backpack Bought this on a recent trip to REI in Greensboro to get a new 0 degree bag. Used it on pack from Cade's Cove to Clingman's Dome. Was very light and compacted well. Started out hiking in 40 degree and then weather turned cold and wet. Added a small liner I had brought and slept nice and toasty at 15 degrees and windy in shelter. Love it. Think it will be great in all temps.
