Platypus are water geeks, laboratory technicians, researchers, designers, managers, directors, worker bees, and people with useful degrees...

…and they also like to laugh, pull pranks on each other, get outdoors and ride, hike, run, paddle, climb, rip, rail and try to enjoy every sip of adventure we can get.

Platypus is proud of the fact that they make the majority of their hydration solutions here in the U.S.A. in their own factory. And because they believe in what they make, and making it right, they have our own certified, world-class water laboratory, which enables them to research, develop, and test technologies so that you can have safe, effective, and dependable hydration and filtration option.
