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. Poly Tour Fire features Yonex’s Silicone oil Infused Filament (SIF) technology which aids in string snapback for greater spin on the ball. This string is stiffer than other polyester strings by Yonex but has great characteristics. 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.
