Yonex Polytour Rev String

Introducing POLYTOUR REV! As a co-polyester monofilament, this string will give you the needed control to execute your most powerful strokes. Packed with 8 sides, POLYTOUR REV not only puts a tight grip on the ball, it also comes with a SIF (Silicone Oil Infusion), which helps the strings snapback powerfully during impact for extra ball rotation. This co-poly also has above average comfort for a poly-based string, making it an obvious choice for any player who wants a more arm-friendly control string.
