1. A golf club head comprising:
a body having front end, a rear end, a top side, a lower side, a toe end, a heel end, and a hosel positioned at a 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;
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 end 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;
a Y-Z plane defined by the y-axis and z-axis;
a heel opening located on the heel end of the body, the heel opening configured to receive a fastening member;
a head-shaft connection system including a sleeve that is secured by the fastening member in a locked position, the head-shaft connection system configured to allow the golf club head to be adjustably attachable to a golf club shaft in a plurality of different positions resulting in an adjustability range of different combinations of loft angle, face angle, or lie angle; and
a rear weight connected to the golf club head proximate the rear end of the golf club head and proximate the Y-Z plane;
wherein the golf club head has a center of gravity (CG) with a head origin x-axis (CGx) coordinate between about −4 mm and about 9 mm, a head origin y-axis (CGy) coordinate between about 15 mm and about 50 mm, and a head origin z-axis (CGz) 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 between 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 between 250-350 kg-mm2 and less than Ixx;
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 between 350-600 kg-mm2, and Izz is no more than 210 kg-mm2 greater than Ixx;
wherein at least a portion of the crown is formed from a first fiber reinforced polymer material;
wherein a portion of the face is formed from a second fiber reinforced polymer material; and
wherein the second fiber reinforced polymer material is at least partially covered by a polymer cover comprising a textured striking surface for contacting a golf ball at impact.
