String of choice for Grand Slam Champion and World Number 1 Angelique Kerber, Yonex Poly Tour Fire is a durable monofilament string that brings great playability to anyone's game.

Players with big swings can take full advantage of this string because of its stiffness and low power, but offers good comfort thanks to its muted feel.
