The Fusion World Cup Suit is built to meet the high specifications of International Triathlon Union (ITU) professional standards. The suit is made from LYCRA® POWER™. A certified compressive fabric made to enhance performance by reducing muscle vibration, a major cause of muscle fatigue, therefore increasing accuracy and efficiency of movement, and providing superior comfort and fit. (Please note: the Fusion World Cup Suit uses a slightly lighter fabric used than on other Fusion LYCRA® POWER™ products so there is less friction when moving at speed). The suit is designed to ensure optimum glide through the water in non-wetsuit swims but is as equally comfortable under a wetsuit. It is constructed using flatlock stitching for enhanced comfort.
