They are the only bags I have found that I don't frequently wake up with that panicked/tied up feeling. I'm 6'2 215 with wide shoulders.
LOL, great description!
I'm only 5'10" 155lbs, so I can use a smaller bag, but I've had a couple that were tight enough I've experienced that feeling! But I've been using mummy bags for 40 years now and that hasn't happened in a long time.
