Sleep comfortably, even when it’s 20⁰ F outside in the Coleman® Brazos™ Cold Weather Sleeping Bag. The specially-designed, patented zipper system plows through the fabric to avoid snags, even around the bottom corner. The Thermolock™ System reduces heat loss though the zipper, and Fiberlock™ Construction prevents insulation from shifting—extending the life of your sleeping bag. When you’re ready to pack up, the patented Roll Control™ System keeps the bag in place for easier rolling and the stuff sack makes packing and storing a cinch. The sleeping bag is machine washable.
