Even though I've only taken it out on one trip, it's plenty warm, it zips to my girlfriend's REI bag quite nicely, and I think it's even warmer than her REI 15-degree bag. Other brands I've gotten have pretty "optimistic" temperature ratings, but this brand delivers! You can compress it even smaller than the stuff sack they give you, but I called WM and they're pretty cautionary about compressing it any further.

in fact, it was a little too snug for me, so I returned it, but if you don't mind the snugness then go for it. They make a wider model (I forget the name)
