CamelBak Podium Chill 21oz Water Bottle. There's nothing quite like having cool drinks to quench one's thirst during warm days in the saddle, and with the CamelBak Podium Chill 21oz insulated water bottle on board you'll enjoy sweet relief far beyond the capacity of conventional bottles. The secret to the Podium Chill's excellence is its double wall construction that's designed to keep drinks cold twice as long as regular water bottles. CamelBak has also packed the Podium Chill with a litany of additional features, first and foremost by topping it off with their patented spill proof Jet Valve so you can drink freely without having to worry about opening and closing the typical drink interface. No more annoying leaks all over you or your bike! No more struggles to pull open a sticky bite valve with your teeth! Not only that, its TruTaste polypropylene construction guarantees you taste your drink and not the bottle while a wide mouth, screw top make adding ice or cleaning the interior a snap.
