Complete with a new design and a new layup, the Wilson H6 103 Tennis Racquet maintains the lightweight, head-heavy feel that fans of the original Wilson Hammer series cherish, but with more stability and firmness than before. This extra stability is derived from all-new C-Matrix Technology, which adds stiffness to the frame for smoother swings and volleys. Throw in the Perimeter Weighting System for improved torsional stability, and this racket creates a high ceiling for crisp put-aways at the net and an impressive display of power despite its light weight.
