2L Lumbar Resevoir 2.0 25/26

Stay hydrated on the trail with the upgraded Dakine 2L Lumbar Reservoir 2.0—a purpose-built hydration system engineered for mountain bike hip packs. Co-developed with Hydrapak®, this low-profile reservoir features a wide, fold-and-slide top for easy filling and cleaning, along with a molded 3D shape that maintains structure, improves internal fit, and dramatically speeds up drying between rides.

Its Comet Bite Valve is self-sealing, with a one-handed open/lock function for mid-ride ease, while the Plug-N-Play® quick-disconnect hose allows for fast refills without the hassle of removing the whole setup. The Shape-Loc center baffle keeps the bladder flat and stable to minimize sloshing, even on aggressive descents. Made from FDA-approved TPU, the reservoir is BPA- and PVC-free, ensuring safe, long-lasting performance—backed by a lifetime no-leak warranty.

Whether you're replacing a worn-out bladder or upgrading your hydration game, this reservoir offers the perfect blend of ergonomic design and rugged reliability.
