Continuing their line of high quality strings, Volkl V Star is the most durable of the line due to its thicker diameter but does not generate quite as much spin while still offering a solid combination of spin, control, and feel. The string is constructed utilizing a co-polymer matrix in order to combine properties for increased tension maintenance and a softer feel compared to a standard polyester. The thicker gauge of V Star offers a solid feel while the greater elasticity provides additional ball-pocketing for enhanced feel. This string is designed for players seeking greater spin and comfort without sacrificing too much durability. All court players looking for additional power from a control and spin oriented polyester based string, should try this offering from Volkl. Construction: Monofilament extruded co-polyester Color: Silver Gauge: 16/17/18 Length: 660' Need help selecting a string? Check out our Choosing The Right Tennis String guide for more assistance.
