Tired of lying awake at night on late season hunts shivering in a curled up position to stay warm? We've all been there and science tells us that a lack of sleep is detrimental to decision making. Ensure you'll be comfortable at night and sleep well by adding a bag built for the coldest of conditions to your arsenal. With a focus on warmth to weight ratio and pack-ability, the Chilkoot 0° bag utilizes industry-leading materials to achieve an overall weight and temperature rating that is best-in-class. A Pertex Quantum shell adds water and wind resistance to protect the 850 Fill power goose down HyperDRY insulation. This bag is designed with an articulated footbox and differential cut to provide warmth and maintain loft around the body regardless of sleeping position. An articulated hood boasts a uniquely designed insulated neck cuff with an elastic and magnetic closure to seal in heat. A weight conscious 2/3 length reverse coil YKK zipper is paralleled by Dacron tape to reduce zipper snagging. When all put together, the Chilkoot 0° is a high-performance ultralight sleeping bag designed specifically for the most discerning mountain hunter.
