Update or replace your lumbar reservoir. This 3-liter lumbar reservoir is just like the one that comes in our mountain bike hydration packs. The 100-ounce design includes a wide mouth for easy filling and a high-flow valve for efficient drinking. - 3L / 100 oz Dakine x Hydrapak 3D lumbar reservoir w/quick disconnect - Blaster high-flow bite valve w/ shut-off - Quick-disconnect tubing for easier refills - Molded 3D bottom provides better shape inside pack - Molded 3D bottom for much better drying between rides

The Dakine 2L Hydrapak design of the Replacement Reservoir is engineered to be durable and easy to use. The Shape-Loc center baffle adds some rigidity to the shape of the bladder, which cuts down on shifting of water weight while you're in motion and makes for a more resilient design. Meanwhile, the wide-mouth opening and plug-and-play connecters make it easy to fill, drain, and clean. And, of course, it's BPA- and PVC-free.

Trek into unknown adventure with the confidence of clean drinking water. The Crux 2L Reservoir Filtration Kit filtered by LifeStraw carries 2 liters of water that pass through two separate stages of filtration for safe hydration. The Hollow Fiber Filter removes bacteria, parasites, and microplastics and the Activated Carbon Filter reduces taste, odor, and chlorine. The wide-mouth fill port includes a tethered leak-proof cap and ergonomic handle for a sturdy fill. An on/off lever prevents unwanted drips and the Big Bite Valve self-seals after each sip. Hydroguard anti-microbial technology inhibits the growth of bacteria in the reservoir and tube, and all components are free of BPA, BPS, and BPF. Pack assembly is a breeze with an easy-to-load low-profile reservoir baffle and Quicklink System that features an auto shut-off to prevent leakage. Convert into a gravity bag by pairing with CamelBak's Reservoir Gravity Kit (sold separately). Safe hydration, trustworthy filtration.
