1. A golf club head comprising:
- a body portion having a toe portion, a heel portion, a top portion, a sole portion, a rear portion with a plurality of weight portions, a front portion having a face portion with a face portion thickness extending between a front surface and a back surface, and an interior cavity, the body portion being associated with a body portion volume;
an elastic polymer material in the interior cavity, the elastic polymer material being associated with an elastic polymer material volume,wherein the elastic polymer material volume is related to the body portion volume by the equation 0.2≦
Ve/Vb≦
0.5, where Ve is the elastic polymer material volume in units of in3, and Vb is the body portion volume in units of in3, andwherein a greater number of weight portions of the plurality of weight portions are located on the rear portion below a horizontal midplane of the body portion than above the horizontal midplane.
