With double-walled construction to keep water cold twice as long as other bottles, the insulated CamelBak Podium® Chill is the best-of-the-best for delivering cold, consistent cycling hydration. The Mud Cap keeps dirt and dust out of your bottle while the secure cage fit means you'll be able to swig and stow your bottle with confidence. Like all CamelBak Podium® bottles, it features our high flow, self-sealing Jet Valve™, easy-to-clean interface and easy-to-squeeze design. And, of course, it's 100% free of BPA, BPS and BPF.
