Hydration is easier when the water flows fast and the reservoir is simple to manage. The Platypus Big Zip EVO Reservoirs are made for hikers, backpackers, bikepackers and trail riders who want reliable, taste-free water access without stopping to rummage through a pack.

Its high-flow design helps deliver quick, effortless drinking on the move, while the self-sealing HyFLO™ bite valve and shut-off valve help prevent leaks between sips. The wide SlideLock™ opening makes filling and cleaning straightforward, and the quick-disconnect hose allows the reservoir to be removed from a pack without unthreading the drink tube. With a slim 2L capacity and durable, taste-free materials, it is a dependable hydration upgrade for day walks, overnight hikes and long kilometres on the trail.
