Mizuno’s fastest suit yet. Engineered for high-speeds, the GX-Sonic V is built for swimmers seeking top performances. The Multi Racer (MR) model fully supports the core and offers a hip lift sensation. The MR is designed with slightly less compression for increased mobility. This tech suit is engineered with updated Sonic Light Ribtex UW material, which offers increased water resistance for faster movement through the water and increased flotation. This new material combined with the Sonic Line X taping lifts the lower body and supports your entire kick cycle throughout the race. Crush the competition in the GX-Sonic V.
