Frequently Asked Quesetions

The Polar Bottle Sport cap is manufactured by our supplier in Denver.  We assemble the cap on to bottles, and ship it from our Boulder, CO headquarters.

Polar Bottle products are made from PP, LDPE, HDPE, and Tritan™ plastics, which are free of harmful chemicals like BPA and Phthalates. To the furthest extent of current scientific knowledge, none of these plastics contain harmful chemicals that may leach into the liquid contained in the bottle. The well-being of our customers is of the highest priority to our company and plastic safety is an issue we take very seriously.

Polar Bottle products have always been BPA and Phthalate Free.

Yes, Polar Bottle caps are dishwasher and freezer safe.

Yes, all drinking valves on Polar Bottle caps are removable for easy cleaning. To remove the valve, first pull up on the valve until the cap is fully open. Then, add a little pressure to pinch the valve so that you can turn it to the left until the dots on the valve and cap line up. Once the dots line up, simply pull up to remove the valve fully from the cap.

To reinsert the valve, line up the dots again, push the valve fully closed, then twist right to lock in place.

The old style cap fits only the original Polar Bottle, which had a screen printed logo (rather than a design printed on the foil liner), as well as a slightly different shape. We made this change in 2004. All 12oz, 20oz and 24oz made since then are fitted with the standard sport cap.
