By eliminating the "bite open" and "hip-slap shut" actions, the revolutionary CamelBak Podium 21oz Bottle will completely change the way you hydrate while cycling. CamelBak's innovative Jet Valve lets you hydrate immediately without having to open or close a drinking interface. Its self-sealing design eliminates spills, splatters and leaks, so you focus on drinking your water, not wearing it. Lightweight, squeezable body has a high water flow rate and its streamlined, ergonomic design won't compromise bottle grip. Secure lockout dial on cap guarantees leakproof transport.
