Some of the most buzzed about string on the market, Luxilon 4G Rough 125 16L Tennis String Gold is noticeably different from its polyester predecessors in that it has a cushioned feel on impact. There’s no “poly jolt”, and your body will feel happier after hours of play than with most other similar strings. The "rough" version is textured for increased ball bite and power potential, while exceptional tension maintenance gives this string consistency and durability.
