Well, it's definitely a warm bag. Coldest of cold nights in South America were comfortable. Downside: It's big. It doesn't compress worth a damn so it takes up a bunch of space in your sack. If I could go back in time, I would have spent more to buy a down bag with a Pertex shell. But this certainly has the warmth.
