Introducing Gosen G Tour 1, a medium firm co-polyester that rewards big swings with exceptional control. The low power level will enable you to swing bigger when adding pace and spin to your shots. Gosen has designed G Tour 1 with silicone oil coating so that strings snapback during contact in order to increase the ball's rotation. A great option for intermediate and advanced players looking for a comfortably firm control string that will keep the biggest strokes on target.
