New material to reduce water resistance. Employs a graphic that combines a brushstroke-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. It adopts a new material that pursues further weight reduction and water resistance reduction, 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, it reduces discomfort caused by fabric tension during adduction of the legs, and has a structure 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, and 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 for the front body parts), and by processing the material surface flat, it reduces water resistance by a maximum of approximately 2.3%. In addition, it considers ease of use in the water, such as increasing the stretchability in the longitudinal and circumferential directions of the body so that athletes can fully demonstrate their performance.
