The bag for people who camp in pairs, this double mummy is lighter, warmer, more compact, more efficient and generally less hassle than any combination of zipped together single bags. Each side has its own 70″ zipper for individual temperature control. If you camp in threes or fours you can zip another Kaskawulsh to yours. The bag is large enough to provide matchless sleeping comfort for both occupants. With a total weight of only 6 1/2 lbs. the Kaskawulsh is also a favorite with single claustrophobes.
