Being a stomach and spread-out sleeper, I *need* a rectangle bag. No mummies for me. This bag is very comfortable for me, and it integrated perfectly with my NeoAir mat. I absolutely love the double zips, and think it'll be a great bag to travel with. The only thing that is disappointing is that it is only rated as a 25F bag. I haven't tried it down that low yet, but it feels thin enough that I am skeptical that it would be comfortable at 25F. I would like to see it stuffed just a little fuller with down, or, as an alternative, to have a thin down blanket that can adapt this for colder temps. In fact, I've purchased just that, hoping that I can build a camping quilt out of a Double Black-Diamond down throw, to add as an extra insulation layer to the top of this bag when I'm traveling in cold areas. If they made a 0F or 10F bag that is similar, I'd be at 100% satisfaction.
