Long rides in the blazing sun are no match for the insulating power of CamelBak's Podium Big Chill Bottle. It boasts a double-wall polypropylene construction with an airtight layer of insulating foam to keep your drinks nice and cool. To prevent tastes, odors, and bacteria, it's lined with CamelBak's HydroGuard. This huge bottle also sports CamelBak's easy-sipping, self-sealing Jet Valve that even has a shut-off switch for leak-proof carrying. The Podium is dishwasher safe and fits in any bottle cage; plus, you don't have to use the ol' hip-tap to close it.
