OG exemplary drawing
 
1. A golf club head comprising:
a body having front end, a rear end, a top side, a lower side, a toe side, a heel side, and a hosel positioned at the heel side of the body, a sole positioned at the lower side of the body, and a crown positioned at the top side of the body, the golf club head having a volume greater than 400 cm3, a head mass less than 220 grams, and an interior cavity;
an adjustable head-shaft connection assembly coupled to the hosel and configured to adjust an orientation of the golf club head relative to a golf club shaft, wherein the adjustable head-shaft connection assembly includes a shaft sleeve having a sleeve mass, and a sleeve screw having a sleeve screw mass, wherein the adjustable head-shaft connection assembly is configured to have at least four discrete positions and produce a maximum loft change of at least 3.0 degrees by changing a rotational position of the shaft sleeve within the hosel;
a weight having a weight mass, and a weight port configured to receive at least a portion of the weight, wherein the weight port is located proximate the rear end, and the weight mass is greater than a sum of the sleeve mass and the sleeve screw mass; and
a face positioned at the front end of the golf club head and including a striking surface having a face thickness that varies, the striking surface having a club head origin positioned at a geometric center of the striking surface, the club head origin defining a head origin coordinate system including a z-axis extending through the head origin in a generally vertical direction relative to the ground when the golf club head is in a normal address position, an x-axis extending through the head origin in a toe-to-heel direction generally perpendicular to the z-axis, and a y-axis extending through the head origin in a front-to-back direction and generally perpendicular to the x-axis and to the z-axis, wherein the x-axis extends in a positive direction from the club head origin toward the heel side of the golf club head, the y-axis extends in a positive direction from the club head origin towards the rear end of the golf club head, and the z-axis extends in a positive direction from the club head origin towards the crown of the golf club head;
wherein the golf club head has a center of gravity (CG) with a head origin x-axis (CGx) coordinate between about −2 mm and about 8 mm, a head origin y-axis (CGy) coordinate between about 15 mm and about 50 mm, and a head origin z-axis (CGz) coordinate between about −8 mm and about 0 mm;
wherein a moment of inertia about a golf club head center of gravity x-axis (Ixx) generally parallel to the head origin x-axis is 250-500 kg·mm2;
wherein a moment of inertia about a golf club head center of gravity y-axis (Iyy) generally parallel to the head origin y-axis is 250-350 kg·mm2 and less than the Ixx; and
wherein a moment of inertia about a golf club head center of gravity z-axis (Izz) generally parallel to the head origin z-axis is 3-50400-600 kg·mm2, the Izz is no more than 210 kg·mm2 greater than the Ixx, and the Izz is at least 160 kg·mm2 greater than the Iyy.
