Yeah, let me say again that I don't think many of the people above are right. Nothing from Western Mountaineering or Integral designs will fit him. I also own and have tried bags from Feathered Friends and LLBean and haven't had any luck. Feathered Friends custom made me a Rock Wren that fit when I was about 260 but it only fits now if I keep my arms on the outside.
I made a quilt that works really well 3 season, if you're into doing something like that. Combined with my 25" pad it's really comfortable.
Wrong. The Integral Designs Broad designs will.
