One near-tragedy sparked an idea. A group of engineering students at the University of Karlsruhe decided to reinvent water safety from the ground up. The result: RESTUBE, a compact flotation device that's reshaping how people approach water activities.
RESTUBE is small enough to wear around your waist or harness without restricting movement, yet powerful enough to save your life. One pull of the trigger and a yellow buoy inflates in seconds, providing instant buoyancy when you need it most. Unlike traditional life jackets, RESTUBE lets you explore freely until the moment you need protection.
