【High-Speed Swimsuit】 Aquaforce Lightning SSS Size Used several times in competitions when wearing sizes 130 to 140. Both the Arena mark and the FINA mark have no peeling or damage. It seems to be quite tight as it is a high-speed swimsuit. New high-speed swimsuits cost over 15,000 yen, so I think it's a good choice for a high-speed swimsuit debut for those who have been conscious of their time. Further weight reduction. New material that reduces water resistance. Employs a graphic that combines a brush-stroke-like image with the ASICS letters. From the start to the finish of the race, it maintains the swimmer's posture in a "straight line" and pursues the reduction of water resistance with the "CORESTINGER" function. Employs a new material that further reduces weight and water resistance, and enhances stretchability. "RAiOstream2+" for swimmers who prefer a firm hold around the waist. ・CORESTiNGER concept inheritance 【What is the CORESTiNGER function?】 From the start to the finish of the race, it maintains the swimmer's posture in a "straight line" and reduces water resistance. By placing soft fabric on the outside of the thighs, discomfort caused by fabric tension during adduction of the legs is reduced, and a structure is adopted that places material that exerts tension from the crotch to the thighs, supporting a straight posture with the legs closed. The waist area has fabrics with different rigidity placed in appropriate places, adjusting the pressure distribution on the pelvis, making it easier to keep the waist in a high position. In addition, to reduce drag, the number of parts has been kept to a minimum, and the surface has been designed to be less uneven. With these functions, it becomes easier to maintain speed, especially from the second half to the last. The material is approximately 27% lighter compared to the conventional model (※comparing the weight of the material used in the front body parts), and by processing the material surface flat, water resistance is reduced by a maximum of approximately 2.3%. In addition, to allow athletes to fully demonstrate their performance, consideration has been given to ease of movement in the water, such as increasing the stretchability in the longitudinal and circumferential directions of the body.
