  1. Works great

    It's a great sleeping bag. I'm 6'2" and 190 lbs and I have lots of room at the feet and shoulder areas. Easily rolls up tight. It would be nice if it came with a compression sack but I just bought one. It keeps you warm at the temperatures advertised. on Aug 9th 2017

  2. Spacious, warm, awesome

    I've had a few sleeping bags over the year with boy scouts and this one is sick! Too warm? Zip your feet out. Too cold? Zip em back in and pull in the mummy top. Pretty tight getting it back into the bag but it's probably because it's new. Might purchase a stuff pack for backpacking. on May 14th 2016
