Abstract
A golf club head comprising a body and a plurality of stiffening members and satisfying the equation Vballnorm≧0.0356x+140.82 is disclosed herein. The body comprises a face section, a sole section, and a crown or return section, and defines a hollow interior. Each of the plurality of stiffening members extends from the crown or return section to the sole section within the hollow interior to reduce stresses placed on the face section during impact with a golf ball. The stiffening members are all located within 1 inch of a rear surface of the face section measured along a plane normal to the center of the face, and are spaced a distance of 0.500 to 2.00 inch from one another within the hollow interior.
