Combining the thermal properties of an insulated vacuum bottle with the lightweight, flexible features of a plastic bottle, the Polar Bottle is the ideal choice for active people. Simply fill with liquid and ice and hit the trail. For even longer cooling power, fill your Polar Bottle and store it in the freezer before use.
