The Men's Dakine Drafter Bike Hydration Backpack 14L is a spacious pack for mountain bikers. It all starts off with an AirLite Suspension back panel and breathable ergonomic shoulder straps to maintain comfortable carry while you're zipping this way and that on two wheels along the trails. An included 3L Dakine x Hydrapak lumbar reservoir keeps you hydrated for long adventures, while ensuring weight stays low and close to the body when tucked into the hydration compartment. Organization pockets and straps make it incredibly easy to pack and locate gear as you need it, plus it's DK Impact Spine Protector compatible (sold separately) for increased safety.
