Yonex PolyTour Fire 125 – 12m Set (Red)

The Yonex PolyTour Fire 125 is a high-performance polyester string designed for advanced players with medium-to-fast swing speeds. Delivering explosive snapback, impressive control, and a lively feel, this string features SIF (Silicone Infused Filament) Technology, developed in collaboration with NANODAX, to reduce friction and boost spin potential.

With a round monofilament profile, PolyTour Fire provides excellent ball pocketing and a responsive feel. It’s a favourite among aggressive baseliners and all-court players looking for a blend of power, spin, comfort, and control—especially those who enjoy hybrid setups.
