PLATYPUS HYDRATION HYPERFLOW BITE VALVE
Platypus
Platypus Hydration HyperFlow™ Bite valve
The new improved HyperFlow™ Bite Valve has twice the flow of the previous Bite Valve. It's soft, drip-free, and easy to hold in the mouth. It can also be pulled apart to remove built-up grunge.
Now available as a shut-off valve to completely eliminate any chance of drips or leaks when accidentally squeezed.
