Whether around water, while swimming or stand-up paddling, for training or in competition. Just wear it stoved in the compact pocket to have your focus even more in the moment. Restube Active is also a good choice for fishermen, for river fishing or on a boat, in lake or in the sea. Pull the trigger and 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 or drag it behind you. You also can share the buoyancy with others, which makes it the ideal companion in open water. It is reusable by screwing in a new original 16g CO2 cartridge and very easy to repack.
