1. A wood-type golf club head comprising:
a cup comprising a forward portion of the club head, including a hosel, a forward portion of a crown, and a forward portion of a sole, wherein the cup comprises a cup material and has a cup mass of at least 75 grams;
a face portion at a front end of the cup, the face portion including a geometric center defining an origin of a coordinate system when the club head is ideally positioned, the coordinate system including an x-axis being tangent to the face portion at the origin and parallel to a ground plane, a y-axis intersecting the origin being parallel to the ground plane and orthogonal to the x-axis, and a z-axis intersecting the origin being orthogonal to both the x-axis and the y-axis;
a rear ring formed separately from the cup and coupled to heel and toe portions of the cup to form a club head body, the club head body defining a hollow interior region, a crown opening, and a sole opening, wherein the rear ring comprises a ring material having a density between 1 g/cc and 3 g/cc and a rear ring mass of no more than 50 grams, and defines a rearward most point of the club head having a skirt height of at least 20 mm, and the ring material is different than the cup material;
a crown insert coupled to the crown opening;
a sole insert coupled to the sole opening; and
a rear weight coupled to a rearward portion of the rear ring, the rear weight comprising a material that has greater density than the rear ring, the rear weight having a rear weight mass of no more than 40 grams, having a rear weight origin y-axis coordinate of 90 mm to 120 mm, and a rear weight origin z-axis coordinate of −30 mm to 10 mm;
wherein the club head defining a center of gravity CG, the CG being a distance CGy from the origin as measured along the y-axis of 30-50 mm, a distance CGz from the origin as measured along the z-axis of less than 2 mm, and an elevation Zup measured vertically from the ground plane;
wherein the club head has a center-face y-axis (CFY) distance of 9-18 mm and a face progression (FP) distance of 12-21 mm, and a difference between the FP distance and the CFY distance is 2-12 mm;
wherein the skirt height is greater than Zup;
wherein the club head has an Izz greater than 450 kg*mm2, an Ixx greater than 300 kg*mm2, and a combined sum of Izz and Ixx of no more than 1100 kg*mm2;
wherein the sole opening has a forward boundary defined by the cup and a rear boundary defined by the rear ring, and the sole insert has a forward portion that is coupled to the cup and a rear portion that is coupled to the rear ring;
wherein the sole insert extends from the heel portion of the cup, across the sole opening, and to the toe portion of the cup; and
wherein a ratio of the cup mass to the rear ring mass is greater than 3.
