The arena carbon cage, unique to the range, holds and compresses the muscles perfectly in place. Designed for long distances, it is the ideal suit for backstroke, breaststroke and individual medley. The low profiled bonded seams are strategically placed: they run up the front of the quads, curving outwards and upwards over the hips. The rear seams run straight up each hamstring, continuing over the glutes. The elasticized tapes are designed to store potential energy which is released during dives, kicks and turns, to efficiency and provide the legs with maximum mobility. The perfect mix of flexibility and compression. Patent pending V-Flex technology.
