Whether on the beach, or while you're swimming or snorkeling. Wear the compact pocket to have a better time in the water. Pull the trigger and the yellow Restube buoy inflates within seconds. Restube beach provides enough buoyancy (50N) for adults and children from 10 years and up in swimwear. Just lean over it to lift your head out of the water. Wave with the buoy to catch attention or by dragging it behind you. Restube is reusable by screwing in a new original 11.9g CO2 cartridge and very easy to repack.
