Aquasack
The Aquasack is the ultralight and less expensive version of our Aquatherm using reflective bubble insulation. The Aquasack is an insulated bag that completely surrounds a standard 32-ounce Nalgene bottle with half-inch foam and a reflective insulation material. These sacks help prevent water from freezing while winter camping or mountaineering. They also work great for keeping hot drinks hot in the winter and cold drinks cold in the summer. A hook and loop fastener allows easy attachment to your pack or hip belt. It has a draw-cord opening with an inner insulated lid. The outer liner is constructed of 210 denier pack cloth. (Bottle not included) Colors: Assorted
