What Our Gearhead(R) Experts Are Saying:"This 2L Lumbar Reservoir 2. 0 is a serious upgrade for my hydration setup. The wide mouth makes it easy to fill up and clean, and the new bite valve is perfect for quick sips on the trail. Plus, the 3D bottom design keeps it nicely shaped in my hip pack, so it doesn't slosh around. It's a must-have for anyone with a Dakine hip pack!"Designed for seamless hydration on the trail, the DAKINE 2L Lumbar Reservoir 2. 0 is built to make every sip easy, refreshing, and leak-free. Perfectly compatible with Dakine's mountain bike hydration hip packs, this updated reservoir combines the trusted Dakine x Hydrapak quality with several thoughtful upgrades. The wide fold-and-slide opening makes refilling and cleaning effortless, while the lightweight Comet Bite Valve is self-sealing and can be opened or locked with a single hand for convenience on the go. We especially love the 3D-molded bottom that shapes neatly inside our pack, stabilizing the water and drying quickly between rides. Crafted from FDA-approved, BPA- and PVC-free materials, this reservoir is a reliable, no-leak solution that keeps us hydrated on all our adventures.
