Fusion Reservoir Launch

An Endless Reservoir of Innovation

From the rugged Crux® to the fast and light Fusion™, or the Fusion™ Group Reservoir, we’ve got you (and the crew) covered for every adventure.
IV in a tube sock


34 years ago, the world’s first hydration bladder was born in our founder's backyard. With nowhere to go but up from that early prototype (literally an IV bag shoved into a tube sock) we continued to innovate. And for 2022, we're introducing our most advanced product series yet. After countless hours and numerous versions, it’s time to meet the most functional and user-friendly hydration reservoir on the market—the Fusion reservoir.
