RSVR Hydration is an athlete driven hydration system that disappears on your back.

Hydration bladders were originally based off medical IV bags. They were designed decades ago and have not changed much since. They prioritize storage, not performance and make compromises in order to accommodate a wide variety of consumers.  RSVR is a hydration system purpose built for athletes. It features a patent-pending design that contours to the body. The result are improved stability and a profile so slim you’ll forget it’s there until you need it.
RSVR also goes beyond hydration with HeatSync technology helping athletes recover on the go. The internal baffles control movement and store more fluid in less space while a TRU Zip closure provides direct access for easy filling on the go. The RSVR system is designed to be modular. With optional front vest, insulators and varying capacities, it can be tailored to your unique adventures .
 
The result is a lighter, faster, more configurable system. It is built specifically for modern endurance and performance needs. RSVR isn’t an iteration. It’s a redesign of hydration from the ground up.

The RSVR Hydration System is available through Kickstarter now and will ship to early supporters in August 2026.

“Traditional bladders feel bulky on your back. RSVR feels engineered. The profile is slimmer, the weight distribution is better. The under-arm hose routing is the most natural setup I’ve used.” RSVR Product Tester
