Yonex POLY TOUR REV is another impressive addition to the POLY TOUR string family. Whereas other brands highlight a special coating for their string, Yonex's SIF technology infuses silicon oil with the monofilament material during the manufacturing process. The technology vastly improves the string's snapback and the effect lasts much longer than a simple coating. Another spin-enhancing aspect of POLY TOUR REV is the subtle eight-sided shape. The shape allows REV to slide against itself for greater interaction between the mains and crosses. REV is a high control string that does an impressive job with tension maintenance as well.
