This swim buoy from Cressi is an extremely hydrodynamic swim buoy, made with high quality materials and components. Even in the toughest conditions, the hydrodynamics are improved by a tapered design. The red orange fluorine fabric makes for enhanced visibility and the brilliant finish of the material ensures an ideal slide. An internal compartment watertight with water tightness system is particularly effective, with rigid soul. The inflator also comes with safety closing screwing.
