Yonex Polytour Fire 125

The YONEX Poly Tour Fire Tennis String is a great string for big hitters looking for extra spin potential and precision shot-making. This new Silicone oil Infused Filament (SIF) technology--monofilament infused with Silicone oil--allows big hitters to experience ultimate spin from intense snapback speeds. A greater snapback produces a powerful spin. SIF Technology allows the string to move faster than conventional models, increasing spin.

Construction: Monofilament Polyester with high polymer polyester
