Yonex Poly Tour Air 125 is a comfort-focused polyester tennis string designed for players who want the control of a monofilament with a softer, more forgiving response.

The 1.25 mm gauge provides a practical balance of control, feel, and spin potential, making it an appealing option for players seeking comfort without switching to a multifilament string.
Intermediate to advanced players who prefer a softer polyester string with dependable control and improved comfort. Particularly suitable for players who find conventional polyester strings too stiff but still want a controlled response during full swings.
