I bought the regular size. It is warm with my sleeping bag liner in it. 50 degrees is probably the lowest I’d sleep in it. I’m 5’6” and medium build. It is a little snug. It comes all the way over my head and has a draw string but it is tight around my shoulders. Built very well though. The zipper doesn’t snag. The foot box is wide enough for a little movement but not much. Over all I’m satisfied with it. But I’ll be getting a warmer one for winter.
