The buoy is a double-chambered buoy with an air chamber and a protective outer coating. It is made of abrasion-resistant 420D nylon. The fluorescent red color makes it highly visible: 80 cm x 30 cm. The buoy has a double internal chamber for increased safety. If one of them is punctured, the buoy will always remain on the surface thanks to the other chamber. The three pockets are very practical for storing various accessories. A stabilizing lead makes this buoy very stable even in rough seas and when the upper compartments are occupied by heavy objects.
