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.
