Yonex PolyTour Rev
Yonex Polytour Rev is another great addition to the POLYTOUR line. Yonex' SIF technology infuses a silicon oil with the monofilament material during the manufacturing process. This technology improves the string's pop and has a lasting effect. Another spin-enhancing aspect of Polytour Rev is its eight-sided shape. This shape allows it to slide against itself for greater interaction between the mains and crosses.
