Combining the thermal properties of an insulated vacuum bottle with the lightweight, flexible features of a plastic bottle, Polar Bottle’s insulated water 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 insulated bottle and store it in the freezer before use. Either way, it will keep liquids cold twice as long as conventional water bottles.
The double-wall construction of the Polar insulated water bottles creates a thermal barrier of air to keep heat out and cold in. Foil layers reflect solar rays for additional thermal protection.
Polar Bottle has never used BPA in any water bottles.
