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, a front portion having a face portion with a face portion thickness extending between a front surface and a back surface, at least a first weight portion above a horizontal midplane of the body portion and at least a second weight portion below the horizontal midplane, 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;
wherein the interior cavity is associated with an interior cavity volume, and wherein the interior cavity volume is related to the body portion volume by equation 0.2≦
Vc/Vb≦
0.5, where Vc is the interior cavity volume in units of in3, Vb is the body portion volume in units of in3, and Ve≦
Vc, andwherein a distance between the at least second weight portion and the back surface of the face portion is greater than a distance between the at least first weight portion and the back surface of the face portion.
