We've been doing business with Polar Bottle for some time now. That being said, we recall the first innovation, the Polar Insulated Bottle being a huge leap forward in insulated bottles. Fast forward a few years and Polar Bottle still offers up compelling reasons to be relevant. The new ZipStream™ cap/valve system features a self-sealing valve that also can be removed for easy, effective cleaning. The valve’s design prevents the bottle from leaking even in the open position, and allows pressure to build inside the bottle when squeezed releasing a powerful flow of water.

While the ZipStream™ Waterbottle Cap can be purchased with new bottles, every user of a sport Polar Bottle can upgrade to the new design. All Polar Bottle products are, and always have been, BPA-free and Phthalate-free, so you will confident about the health and safety of the users. Upgrade or simple replace your existing Polar Bottle cap with the ZipStream™ and drink cool refreshing liquids with less effort and more confidence that your bottle cap is clean. Return to Top
