Yonex Polytour Pro is one of the most widely used polyester strings on the ATP and WTA tours, trusted by professionals including Nick Kyrgios for its combination of performance and playability. Unlike many tour-grade polyesters that prioritise stiffness and control at the cost of comfort, Polytour Pro uses a softer compound that maintains excellent performance characteristics while remaining more forgiving on the arm.
The softer construction creates a more elastic string bed that returns energy efficiently Polytour Pro plays with more power than its co-poly stiffness category might suggest, generating natural depth from the string’s lively rebound alongside the spin potential and directional control that polyesters deliver. The result is an unusually versatile co-poly that suits a range of playing styles rather than narrowly targeting spin-seekers or flat-ball strikers.
At 1.25mm, Polytour Pro provides solid durability for competitive and training use. Tension maintenance is good for a poly of this softness; it settles slightly from initial stringing tension but maintains a consistent playing feel through its lifespan. The string performs well at both higher control tensions and lower power-friendly tensions, giving stringers and players flexibility in setup.
An excellent full-bed string for advanced players who want co-poly performance with a more comfortable, accessible feel. Also a strong choice for the mains in a hybrid setup paired with Yonex’s own multifilament crosses. Sold as a single strung set.
