Swix Triac racing suit is designed for the perfectionist who does whatever it takes to get from start to finish as fast as possible. Extensive testing and development has resulted in the most awesome suit we've ever made! Body mapping technology helps to provide optimal combination of ventilation and fit. Power stretch is used around the back and thighs to provide proper compression around the largest muscles. Elastic 'high friction' band around ankles and wrists ensures that the suit does not slip.
