Polar Bottle ZipStream 24 oz - Insulated Cycling & Sports Water Bottle with High Flow Cap - (24 ounce, Orange)

The Zipstream cap features 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 the powerful burst of water you need to push you to the front. The patented Polar Bottle water bottle features an insulating layer between two walls of plastic, so it keeps liquids cool twice as long as other water bottles. The Made in America bottle fits standard bike water bottle cages and features a convenient, removable carrying strap. All Polar Bottle products are, and always have been, BPA-free and Phthalate-free.
