Yonex Poly Tour Spin is a shaped string that really grips the ball for more spin potential and durability. The pentagon shape of this string is very precise and helps you get your ball divingback into the court. Yonex pre-stretches their string under controlled temperatures for better performance and tension maintenance. A durable shaped string that is used on the WTA tour by Sabine Lisicki, Poly Tour Spin will bring a new dimension to your game to give you an edge.
