Super warm, packs down really well, and the hood is great!

So warm!

I owe this sleeping bag my life (joking - kind of?) Camping in Colorado means it is cold at night even in the middle of summer, and this sleeping bag is everything to me. 32 is the coldest I've tested it at but I can imagine it being able to handle much colder. Also the lining inside is so soft. My only complaint is the zipper is tough, but that's a small thing.

Good and warm. Think I might have gotten a left-hand one by accident. Fits well.
