Enduro and gravity riders are going bigger and faster every year. It's time for a pack that can keep up. CamelBak has the answer: the K.U.D.U. 18. The K.U.D.U. elevates the hydration pack with a foam spine protector. It's a lightweight foam that moves with your body and can take multiple impacts. And of course the pack carries 3 liters of fluid and a bunch of gear in the easy-to-reach, well-organized way that CamelBak is famous for. With dual compression straps, overflow storage is easy, too—you can even carry your helmet and pads. Further ingenious features like an integrated rain cover, a load-stabilizing suspension harness, ventilated back panel, and even a removable tool roll makes this pack a must have for those enduro and gravity riders pushing the sport and themselves.
