A high-quality bag that is comfortable to sleep in even cooler weather. For a few nights I have been sleeping outside in late summer / autumn and the cold has not gotten hit! The long model is at least sufficient for a 195cm tall user in terms of its length, but the model is moderately narrow so there is no room for maneuver for a richer man. Personally, though, I’m used to sleeping looser, so this is completely a matter of getting used to, and the bag specifically has a narrower pattern. The big plus for myself is the zipper in the middle that gives a certain sense of freedom especially when staying in a hammock. I have been happy with my purchase!
