Description
Water is a necessity either living in your house or while on a trip. Granite Gear Aquatherm is what you need to keep your water from boiling or freezing while mountaineering, climbing, hiking, or camping. It is basically an insulated bag with 1/2 inch foam with a reflecting insulation material that completely surrounds the standard 32 oz Nalgene bottle and keeps the water at the required temperature.
The Aqua Sack helps prevent the water from freezing or getting hot. You can also keep two sacs, one for hot water and one for cold water. The sack has a daisy chain and a draw-cord opening with an inner insulated lid. It is less expensive than the Aquatherm, but you have to buy the bottle separately.
