Polar BottlePolar Bottle® is the original insulated plastic sport bottle. It keeps liquids colder longer than other water bottles. Polar Bottle 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. Made in America, Polar Bottle is popular throughout the world.
