The specially-designed, patented zipper system plows through the fabric to avoid snags, even around the bottom corner. The Thermolock™ System reduces heat loss through the zipper, and Fiberlock™ Construction prevents insulation from shifting, extending the life of your sleeping bag.

The sleeping bag fits heights up to 6 ft. 4 in. and is machine washable.
