28. A golf club head, comprising:
a front portion, a rear portion, a sole portion, a toe 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, wherein the second piece is separately formed and attached to the first piece, and defines at least a portion of the rear portion;
a face insert, made of a face insert material having a face insert density, attached to the first piece and having a face insert width and a face insert center, wherein a projection of the face insert center downward along a face portion plane intersects a horizontal ground plane to define a ground center location and a ground center Y-axis;
a sole plate, made of a sole plate material having a sole plate density, attached to the second piece at the sole portion of the golf club head;
a weight made of a weight material having a weight material density greater than each of the first material density, the second material density, and the sole plate density, wherein the weight is attached to an exterior portion of the second piece; and
a center of gravity (CG) having a CG x-axis, a CG z-axis, and a CG y-axis, and located a CGy distance behind the ground center location in a direction of the ground center Y-axis; wherein:
the first material density is greater than at least one of the second material density and/or the sole plate density;
the weight is located rearward of the CG x-axis with at least a portion of the weight is located below the CG y-axis;
the sole plate extends from a toe side of the CG y-axis to a heel side of the CG y-axis,
the CGy distance is at least 30 mm and no more than 50 mm;
a moment of inertia of the golf club head about the CG x-axis (Ixx) is at least 2,989 g·cm2 and no more than 10,000 g·cm2;
a moment of inertia of the golf club head about the CG y-axis (Iyy) is at least 1,000 g·cm2 and no more than 3,500 g·cm2; and
a moment of inertia of the golf club head about the CG z-axis (Izz) is at least 4,000 g·cm2 and no more than 14,000 g·cm2.
