Yonex Poly Tour Rev 125 is a spin-focused polyester tennis string designed for players who generate pace and topspin from the baseline. Its eight-sided profile increases ball bite, helping aggressive hitters produce heavier shots while maintaining control on full swings. Silicone Oil Infused Filament (SIF) technology reduces friction between strings to encourage snapback and additional spin. The 1.25 mm gauge offers a practical balance of spin performance and durability.
Intermediate to advanced players with medium-to-fast swing speeds who prioritize topspin, precision, and a controlled response. Best suited to aggressive baseliners comfortable with the firmer feel of polyester strings.
