Abstract
A golf club head is described having a heel portion, a sole portion, a toe portion, a crown portion, a front portion, a rear portion, and a striking face, the front portion having an upper front portion and a lower front portion. In certain examples, the upper front portion is described as made of a first material and the lower front portion made of a material different from the upper front portion. In particular examples, an aft body is described having at least a portion of the crown portion and a portion of the sole portion, the aft body being made of a non-metallic and metallic material. In further particular examples, the golf club head is described as having a D1z ratio of between 0.5 (kg mm3)/cm3 and 6.2 (kg·mm3)/cm3.
