Yonex POLY TOUR REV

Tennis strings: The Yonex POLY TOUR REV is designed primarily for players who play aggressively from the baseline with a medium to fast swing and prefer a spin game. The SIF (Silicone Oil Infused Filament) technology has silicone oils that are incorporated deep into the string's polymers. This reduces the mutual friction and ensures a higher snapback speed, increased power and, above all, a better spin game.
