Some of the most buzzed about string on the market, Luxilon 4G is noticeably different from its polyester predecessors in that it has a cushioned feel on impact.

The power level is slightly lower than previous generations, which should aid 4G’s target player. Color: Gold Construction: Co-polyester Gauge: 16G (130mm) Length: 40'
