Restube for all-round & athletic use – while swimming or stand-up paddling, for training or in competition. Wear it stoved in the compact pocket, when you pull the trigger the yellow Restube buoy inflates within seconds. Restube active provides enough buoyancy (75N) for adults, just lean over it to lift your head out of the water. Wave with the buoy to catch attention. You also can share the buoyancy with others. It is reusable by screwing in a new original 16g CO2 cartridge. Restube active offers a high level of wearing comfort thanks to the alternatively vertical or horizontal attachment.
