Yonex Poly Tour Pro

Unlike many stiff polyester strings that can feel harsh, the Poly Tour Pro 125 uses Silicone Oil Infused Filament (SIF) technology. This creates a softer, more comfortable feel on impact without sacrificing the durability or control expected from a monofilament string.

While polyester strings are generally firmer than multifilament options, the Poly Tour Pro 125 is known for being one of the more arm-friendly options in the monofilament category. If you are sensitive to vibration, it is a solid choice, though you may want to pair it with a softer racquet or lower tension.

The 1.25mm (16L) gauge offers a balanced middle ground. It is thick enough to provide good durability and control, but thin enough to allow for better ball bite and spin potential compared to thicker 1.30mm gauges.

Like most polyester strings, the Poly Tour Pro 125 will experience some tension loss over time. However, its construction is designed to be more stable than many competitors, meaning it maintains its playing characteristics for a respectable period before needing a restringing.

Yes, this string works very well in a hybrid setup. Many players pair it with a softer multifilament or synthetic gut in the crosses to gain extra comfort and power while keeping the durability and spin of the Poly Tour Pro in the mains.
