Yonex V-mass 260 Fairway Wood. The Yonex V-mass 400 Fairway Woods and Irons are an extension to the Yonex V-mass 400 family of drivers. Yonex designs into its clubheads the ultimate engineering material - titanium. Integrating 6-4 titanium with exclusive Tungsten Balancing, Yonex delivers an expansive sweetspot and visually appealing clubhead shape. As with the entire family of V-mass woods, Tungsten Balanced weights are strategically positioned. Tungsten Balancing provides solid shots even on toe or heel hits by reducing clubhead twist at impact. The Muscle Power Face technology provides the longest distance attainable in fairway woods. This exclusive design feature provides superior distance without sacrificing accuracy.
