Abstract: A golf club head comprising a deflection feature to increase ball speed and launch distance, while producing desirable acoustics and optimized mass distribution. The deflection feature can include any one of or any combination of an insert comprising a gap or an insert comprising voids. The insert manipulates the mass distribution while allowing face deflection and positively damp vibrations in the club head. The deflection feature can also include a thin uniform sole, a cutout in the top rail, optimized face material, a thin sole, a reinforcement device, or a multi material weight. The reinforcement element transfers stress away from the face into the reinforcement device, allowing face element to bend at impact. The multi material weight is a dual-density weight comprising a higher density weight base portion and a lower density weight shell portion.
