The revised CamelBak Podium Big Chill provides 24oz/710ml of insulated hydration, with an all new faster flowing Jet Valve. A double-walled bottle construction uses closed cell foam technology to keep your drink cold twice as long as a standard bottle and the patented spill-proof, self-sealing Jet Valve allows you to hydrate immediately without having to open or close a valve. With a streamlined, ergonomic design, the Podium is easy to squeeze without compromising bottle grip. The Podium Chill also has a lockout dial with easy to read graphics for leak-proof transport.
