LOVE this bag!!! One of the most satisfying pieces of gear I have ever purchased, and for such a great price. It is cozy warm right down to the rating and resists moisture impeccably (and I live and work in a very wet backcountry environment). It barely takes up any room in my pack, and has two zippers, one on each side, that make venting easy. I am only 5'1", but the bag is super spacious for me, and has an uber-soft interior. Definitely worth buying!
