The Denali sleeping bag is a cold climate mummy bag able withstand frigid temperatures while you keep toasty warm for a good night's sleep. The Denali is offered in two temperature grades -0° and -30°. Its synthetic TechLoft Silver insulation consists of multiple denier staple-length fibers that have a siliconized finish for maximum insulation, loft, and compactness. Insulated chest and zipper baffles ensure heat retention. The Denali offers plenty of sleeping space with its oversized design, but can still be compressed in the included stuff sack for ultimate packing ease. The 210T nylon diamond ripstop shell and 210T polyester liner offer the strength and durability that campers expect from Browning. For your ultimate camping and hunting needs, you won't be disappointed with the Browning Denali.
