Polar Bottle® is the original insulated plastic sport bottle. It keeps liquids colder longer than other water bottles. We innovated the industry back in 1994 by creating a bottle that would actually keep water cool during any outdoor activity. The bottle has evolved in the years since with brightly colored foil liners and patterns and an innovative removable valve system.
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.
Either way, it will keep liquids cold twice as long as conventional water bottles.
