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 & the yellow Restube buoy inflates within seconds. Restube beach provides enough buoyancy (50N) for adults & children from 10 years & 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 & very easy to repack.. The RESTUBE is NOT a Coast Guard-approved life vest as it does not go over your head or wrap around you. It will not help you if you are passed out. It acts as a flotation swim buoy to rest on & easy to swim with
