Ergo Water Bottle

The idea is simple. Keep liquids colder longer. Easier said than done, but the Polar Bottle Ergo has proven that all it takes is a little experience. Designed by a mechanical engineer with skills in heat-loss prevention, this insulated water bottle features reflective insulation technology that keeps your drink cold more than twice as long as a typical water bottle. It's made from recyclable plastic and will put your old water-holders to shame.

Polar Bottle is a Colorado company founded in a garage in Boulder in 1994. Birthed by Robert Heiberger and Judy Amabile, the company aimed to make a bottle that kept liquids colder longer. The founders are still active in the company today and maintain its commitment to locally sourcing material.
