I've never had a mummy bag before, just got one getting ready for a back country hunt in sep. I get a little claustrophobic when I'm all closed up in there. It is a long and I'm 6 foot 2, so I have a little room but not a ton. Has anyone else had this problem and what did you do to manage it? One of my coworkers says you won't notice it after a long day of hunting. I can unzip the bag a bit and that seems to help, but that kind of defeats the purpose.
