A refined 2-liter reservoir for your hydration hip pack. If it's time to replace or update your hydration reservoir, look no further than the freshly updated 2-Liter (70-ounce) Lumbar Reservoir 2.0, which fits perfectly with DAKINE's mountain bike hydration hip packs. DAKINE's tried-and-true Dakine x Hydrapak 3D lumbar reservoir has been further refined for easy use, starting with the improved fold-and-slide wide mouth opening, which makes for easier filling and cleaning. The new lightweight Comet Bite Valve is self-sealing and can be opened and locked with one hand, while the Plug-N-Play quick-disconnect hose makes refills a breeze. The reservoir's molded, 3D bottom provides better shape inside the pack and allows for quicker drying between rides, and it's constructed of FDA-approved polyurethane (TPU) that is both BPA and PVC free. All of that, along with a lifetime no-leak warranty, means that you'll never be thirsty on a ride. Features: 2L / 70 oz.
