The Poly Tour Force is the most powerful string in the Yonex polyester string lineup. Made of a monofilament core but finished with high polymer polyester, this string offers consistent ball pocketing and high-response power. Yonex pre-stretches this string under controlled temperatures for better tension maintenance. This string is ideal for players with a medium to fast swing, especially those that previously played with the Poly Tour Strike.
