After extensive testing on the trails and roads surrounding its Boulder, Colorado, offices, Polar Bottle has unveiled its brand new ZipStream self-sealing cap.
ZipStream is the first Polar Bottle cap to feature a self-sealing valve. 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 burst of water (or whatever you put inside).
The new cap will initially be featured on the BreakAway line of 24oz and 20oz bottles. It will also be offered as a stand-alone accessory to fit all 24oz, 20oz and 12oz bottles.
ZipStream is available from the Polar Bottle online store right now, and will hit store shelves in early April, retailing for $14 and $15 for 20oz and 24oz bottles, and $5 for an individual cap.
ZipStream is dishwasher safe and has a removable valve for easy cleaning. The cap’s valve is bright orange to distinguish it as a Polar Bottle product. It’s also made in the USA and backed by the company’s lifetime guarantee.
“Over the years, feedback from cyclists has driven much of our design changes,” said company co-founder and head of product development, Robert Heiberger, adding that his engineers are continually working to make bottles more squeezable. “The idea for ZipStream came in response to customers who told us that they wanted faster access to their water.”
We have a couple of these bottles on the way to RoadBikeReview test HQ in Colorado, and will let you know how well they actually work asap. In the meantime, for more info visit polarbottle.com.
