Tennis Strings: YONEX REXIS TENNIS STRING
Shop the Yonex REXIS String
Yonex has released a brand new nylon multifilament string called REXIS.
This string is made with the super elastic FORTIMO polyurethane, making it the first tennis string ever to utilize this material. The same material is also used in elastomers for automobiles, as well as in medical tubes.
This string boasts repulsion, durability, and high flex, resulting in a 4%* increase in ball speed and a 21%* increase in durability.
Utilizing the FRF (Fusion of Resin Filament) manufacturing process, gaps between the string’s nylon filaments are completely filled with resin, resulting in a super dense and solid string structure. This lets players experience reduced power loss on their hits. In addition, plasma bonding is utilized to fuse the nylon filaments and resin on a molecular level, increasing string density and durability.
This string has been used by Naomi Osaka (Japan) since the beginning of the 2017 season and she is very pleased with the outcome of the strings.
"The string allows me to get more control on the ball, and it has more pop when I hit,” she commented, praising the new string.
