Familiarity: I've used it several times
I LOVE this sleeping bag. I sleep on my sides (both) so having a sleeping bag without a zipper is amazing. It feels like I have my comforter with me and can cuddle up with the edges of it and sleep like i'm at home.
Additionally, the flap to allow my feet out at the bottom to vent is incredible. I can regulate my temp without having to move my upper body, and the little flap thing doesn't let any cold air in when I have my feet tucked into my bag.
