For hot days on the trail, the Podium® Dirt Series Chill keeps your water cold twice as long as other bottles. 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 cap, easy-to-clean interface and easy-to-squeeze design. And, of course, it's 100% free of BPA, BPS and BPF.
