Used by Naomi Osaka with Poly Tour Strike, Yonex Rexis is A high-end multifilament designed to help players generate power and maintain comfort. Yonex builds extra comfort into this string using a highly elastic FORTIMO polyurethane. The use of a Fusion of Resin Filament (FRF) process fills in the ordinary multifilament string gaps with more flexible material, giving this string greater elasticity and a solid structure. Yonex Rexis also features plasma bonding on a molecular level, designed to enhance ball speed and improve durability. This string will add comfort and neutralise the shock of a stiff racquet or stringbed when used in a hybrid setup.
