Solinco Hyper-G Soft Tennis String is a slightly softer version of one of the most popular spin strings on the market. Hyper-G Soft's unique shape helps grab the ball to allow for explosive topspin from the back of the court. Hyper-G Soft will play more comfortably than Hyper-G but still offer a more controlled response that Solinco is known for.
