16. A golf club head, comprising:
a front portion, a rear portion, a toe portion, a sole portion, and a heel portion;
a first piece made of a first material having a first material density, the first piece is separately formed and defines at least a portion of the front portion and defines at least a forward portion of the toe portion and the heel portion;
a second piece made of a second material having a second material density, the second piece is separately formed, defines at least a portion of the rear portion, defines at least a rearward portion of the toe portion and the heel portion, and is configured to receive an external weight;
a weight made of a third material having a third material density greater than both the first material density and the second material density, wherein the weight is threadably and removably attached to the second piece;
a non-metallic plastic or polymer material sole plate attached to the second piece at the sole portion of the golf club head; and
a center of gravity (CG) having a CG x-axis, a CG z-axis, and a CG y-axis,
wherein:
the second piece is configured to receive the external weight at a position rearward of the sole plate;
the first material density is greater than the second material density and greater than a density of the sole plate;
a moment of inertia of the golf club head about a CG z-axis (Izz) is between about 2,000 g·cm2 and about 14,000 g·cm2;
a moment of inertia of the golf club head about a CG x-axis (Ixx) is between about 2,989 g·cm2 and about 10,000 g·cm2; and
a moment of inertia of the golf club head about a CG y-axis (Iyy) is between about 1,000 g·cm2 and about 10,000 g·cm2;
the first material is a metal material; and
the second material is a polymer material.
