The RESTUBE sports 3 is the third generation of RESTUBE and is used for almost any water sport, from surfing to swimming. The small and lightweight pocket is worn like a belt around the hips or can be mounted on a harness. In case of a critical situation in the water you pull the trigger and the buoy inflates. You can hold onto it and gain time to avoid panic or drowning. RESTUBE is reusable by installing a new CO2-cartridge.
