SlumberJack Military Mummy 20 Review

"Very rugged bag, haven't gotten a chace to test it temperature wise yet, but as far as durability, the shell is a polycotton blend, that looks feels and wears like a pair of dickies, it's a bit big at 11x21, and it weighs 5 lbs. 4 oz., but it is the most durable bag i've ever seen"
