Wilson Revolve Tennis String is made for players looking for the maximum spin possible in their game. Revolve is a comfortably firm co-polyester designed for players with long and fast strokes. The unique construction compromised of Crosslink Ester Polymer offers exceptional power while maintaining comfort. The UHMW coating gives the strings the freedom to move around freely and snap right back into place after hitting the ball. This co-poly will deliver More Win by excelling in durability and spin effect, which is specially enhanced by frames with Spin Effect Technology, new from Wilson. Revolve string is great for players who hit hard and want great control and spin - especially from the baseline.
