  • WESTERN MOUNTAINEERING Bison -40 Sleeping Bag, Regular

    Made for extreme mountaineering, the Western Mountaineering Bison is a life-saving bundle made with Gore WindStopper and 850+ fill goose down for 10 in. of heat-trapping loft.


    • 30D fabric backed by Gore WindStopper membrane provides protection from the wind, water resistance, and breathability
    • DWR shell fabric treatment protects the down from spills and condensation
    • 850+ fill European goose down with 10 in. of heat-trapping loft provides longevity, compressibility, and a luxurious drape
    • Baffle construction with 5.25 in. spacing and huge V-block side baffles keep down in place
    • Hood with enough down fill to surround your face and forehead
    • Down-filled Gore WindStopper collar with elastic drawcord; hook-and-loop fasteners fold away to prevent chafing when collar is not in use
    • Durable 2.4 oz. fabric in the foot section protects the bag when you store gear or boot liners at the foot of your bag
    • Inner shell fabric cut narrower than the outer shell to promote proper lofting and to protect the down against compression
    • Interlocking down-filled draft tubes rest side by side to retain their loft as the zipper closes to prevent cold air from entering the bag
    • YKK #5 coil zippers slide with less resistance for years of trouble-free use
    • Stiffening tape along the zippers ensures snag-free use
    • Two-way zipper with locking head for ventilation options
    • Water-resistant stuff sack with handle loop for use on the trail
    • Storage sack to keep your bag lofted when you get back home
