Description: Designed to relieve the swimmer's legs thanks to its buoyancy, the EIGHT "3" Aquaspeed allows you to focus entirely on upper body training. Held between the thighs, the EIGHT "3" helps to consolidate the correct position and movement of the arms while swimming, increase the endurance and strength of the arms, and train the correct way of breathing while swimming. OSEMKA "3" Aquaspeed is a top-quality product made of dense, very durable EVA foam, which guarantees high durability of the product and its optimal properties in water. The asymmetrical, carefully designed profile of the ÓSEMKA 3 gives it better streamlining and hydrodynamic properties than the traditional figure 8. ÓSEMKA 3 is also light and small, so you can easily take it to any swimming pool.
