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.

Try this 1.22mm gauge for slightly more spin and feel but less durability than the 1.30mm version.

• Gauge: 17/1.22mm
• Length:  660ft/200m
• Composition: Co-polyester Monofilament
• Color: Yellow
