For hot days on the trail, the Podium Dirt Series Chill keeps your drink cold twice as long thanks to the insulated double-wall construction. As the ultimate bike bottle for both recreational and competitive cyclists alike, it features an integrated mud cap to keep dirt out of your water, a high-flow self-sealing jet valve, and an easy-to-squeeze ergonomic design. The optimized cage fit means you won't fumble to grab or stow your bottle, and because it's 100% free of BPA, BPS, and BPF, you'll ingest nothing but cold, clean water.
