Fastskin is a label for Speedo products that are designed for the best hydrodynamics in water. It's a swimming equipment designed for racing and performance swimmers to reach the most optimal performance. In the Speedo Fastskin range you will find complete equipment. The main ones are, of course, swimwear, goggles and caps that are homologated by FINA, but you can also find training equipment like kickboards, hand paddles and fins. The main success of these technologies is that Speedo carried out a 3D scan of elite swimmers and, through computer simulation, then conducted research and calculations on the resistance and durability of materials. The unique ultralight LZR Pulse swimsuit fabric + reduces muscle oscillation and skin vibration, and imparts a hydrodynamic shape through compression that is effective to the body, which also increases swimming speed. The glued seams will ensure the reduced friction that are involved in increasing your speed. It also ensures perfect body alignment and freedom of movement. The swimwear have elasticated waistband for better tightening and comfortable wearing. The fastening string guarantees comfort. You can fasten the swimsuit by the string and you don't have to worry anymore that the swimsuit will fall down when you jump in the water. Approved and certified by the International Swimming Federation FINA (Fédération Internationale de Natation). It meets all international standards and allows start at prestigious races.
