Browning McKinley Features The Browning McKinley uses a 2-layer offset construction to eliminate cold spots that can occur with single-layer insulation keeping warmth distributed evenly throughout the bag. TechLoft Silver insulation is made of multi-hole staple-length micro-denier fibers with a siliconized finish maximizing insulation loft and compactness for a -30 degree rating. A contoured hood helps seal in warmth around the head and shoulders an important feature on the coldest nights in camp. The oversized rectangle shape gives hunters more room to move than a snug mummy bag while still trapping heat effectively. A 210T nylon diamond ripstop outer shell resists abrasion and the elements while a brushed polyester liner adds a soft comfortable layer against the skin. Two #10 separating zippers along with an insulated chest and zipper baffle keep drafts from sneaking in through the closure. For transport the McKinley includes a compression stuff sack and roll-up straps making it easier to pack into a vehicle or pack frame. Weighing in at roughly 12 lbs 12 oz the Browning McKinley -30 Degree Sleeping Bag is built for serious cold weather hunting camps and is available for sale at GrabAGun.
