3 days on the AT- Rock Creek to NOC
really enjoyed this bag, especially with a Big Agnes air mattress tucked into the bottom sleeve. I'm 6'2'' and weigh 245 lbs. so leg and shoulder room are important. This bag was excellent in both these areas and I slept comfortably ( had pack pillow tucked into the pouch at the head of the bag) each evening after really grueling hiking. However, the reason that the bag does not get the fifth star is that it would not fit someone over 6' 3"...i found it just came up to my neck with me feet at the bottom of the bag. That being said, this warm weather bag packs light and will more than meet it's temperature rating.
