I'm using this bag to hammock camp in the cold. Slept out in it the other night on my hammock. The temperature was 25 F. I was very comfortable. I also own the Alps 0 degree bag. The Mountainsmith is lighter, packs smaller, and is of better quality. Both are good bags, the Mointainsmith is just better.
