Wilson Revolve Spin is the sibling string to the Wilson Revolve, but offers more spin due to its pentagonal shape.  It is comfortable co-polyester string that provides exceptional spin and control that poly strings are known for.  Featuring a tri-polymer construction with a low-friction additive, this allows Revolve to snap-back, providing more spin with each shot.   Due to the pentagonal shape, the Revolve Spin's durability will not be on par with the Revolve string.  Like any co-polyester, the Revolve Spin is designed for players with long, fast strokes, who do not have a problem generating power on their own.
