Made from open cell foam and coated nylon, this parka is lighter than a thermos. Helps keep soup or tea from freezing in the winter and cool drinks from getting hot in the summer. The Parka has a large zippered opening that fits around Nalgene-style water bottles and a 2" wide webbing belt loop that attaches to your pack's waist belt. An essential item in very cold environments.
