Introducing Signum Pro Yellow Jacket! As a co-polyester monofilament, this string is designed to give intermediate and advanced players the needed control to attack the ball. In addition to its low powered and ultra-predictable response, this string has a hexagonal shape for maximum bite. The result is massive spin potential. With its comfortably crisp feel, this is one of the best values in the co-polyester category.

Try this 1.30mm gauge for slightly more control and durability than the 1.22mm version.
