Hey everyone, I am new to this site so forgive me if this topic has been discussed before. I am a large guy - 6'4", 235 lbs on good day and I am looking for a comfortable sleeping bag for extended pack trips. I want a down, lightwieght bag big enough to fit me comfortably. I like a little space with my sleeping bag as I hate the tight fitting mummy bags. Weight is important, but comfort is more important. Any feedback from some larger folks out there would be appreciated. Thanks
