1. A golf club head comprising:
- a body portion having a face portion, a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity extending between the top and sole portions and being partially or entirely filled with an elastic polymer material;
a plurality of weight portions; and
a plurality of weight ports comprising a first set of weight ports located along a periphery of the back portion proximate to the sole portion and extending between the toe portion and the heel portion and a second set of weight ports located along the periphery of the back portion proximate to the top portion, the weight ports of the first set of weight ports being substantially similarly spaced apart, each of the weight ports of the first set of weight ports having a substantially similar port diameter as an adjacent weight port a the first set of weight ports and being separated by less than the port diameter from the adjacent weight port, each weight port of the plurality of weight ports configured to receive at least one weight portion of the plurality of weight portions, the interior cavity being accessible through at least one of the weight ports of the plurality of weight ports.

15. A golf club head comprising:
-
a hollow body portion having a face portion with a thickness of less than or equal to 1.5 millimeters (0.060 inch), a toe portion, a heel portion, a top portion, a sole portion, a back portion, and an interior cavity extending between the top and sole portions; an elastic polymer material in the interior cavity configured to partially or entirely fill the interior cavity by injection molding, the elastic polymer material being attached to the face portion and configured to structurally support the face portion during impact of the face portion with a golf ball; and a plurality of weight portions coupled to the hollow body portion and located above and below a horizontal midplane of the golf club head; wherein the number of weight portions below the horizontal midplane is greater than the number of weight portions above the horizontal midplane. - View Dependent Claims (16, 17, 18, 19, 20)
