The Podium Dirt Series is the premium bike bottle for mountain bikers who prioritize performance and functionality above all else. 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.
