New for 2009! Subjected to rigorous testing by elite athletes, the groundbreaking CamelBak Men’s RaceBak vest is the first base layer to have its own built-in hydration! An innovative, integrated pocket stores an included 72 oz hydration system, making the Men’s RaceBak ideal for road-biking, mountain biking, running and other aerobic activities.

Dual fabrics combine to create an aerodynamic, high-performance hydration vest. Chafe-free fabric stabilizes the Men’s RaceBak’s hydration bladder and conforms to your body for a snug fit while lightweight, breathable fabrics wick away moisture. A mesh backpanel keeps you cool while insulating the water in the reservoir.

The Men’s RaceBak’s 72 oz reservoir includes an integrated hydration tube and bite valve. An insulated cover keeps the water in the tube cool and protects the tube from wear and tear.

The CamelBak Men’s RaceBak vest comes in S (35"-38" chest), M (38"-41"), L (41"-44") and XL (44"-47") sizes.
