If you're looking for a Sleeping Bag that can take on McKinley-like extreme temps, then turn to this namesake Bag. The cold-climate Bag is known to tackle temps down to -30°F to keep you cocooned in total warmth. Its synthetic TechLoft Silver insulation consists of varied staple-length micro-denier fibers with a siliconized finish for maximum insulation, loft, and compactness. And just like the majestic McKinley, it has an expansive, oversized shape that'll give you plenty of wiggle room. While roomy inside, it still compresses into a manageable size for packing ease. You won't be disappointed with the Browning McKinley for all of your camping and hunting needs.
