Yonex POLYTOUR REV is an octagonal polyester monofilament designed for pronounced spin and control from the baseline.
Its eight-sided profile engages the ball, while SIF (Silicone Infused Filament) technology reduces friction between strings and encourages fast snapback. Yonex recommends REV for medium to fast swings and aggressive topspin play.
This version has a 1.25 mm gauge (16L) and a length of 12 m in the official Bright Orange colourway. The set length is intended for individual racquet stringing.
