1. A wood-type golf club head comprising:
- a body comprising a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head wherein at least a portion of the sole has a total sole thickness less than about 0.9 mm, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown, wherein the body defines an interior cavity;
two or more weight ports formed in the body; and
at least one weight configured to be removably retained at least partially within one of the weight ports;
wherein the head includes a golf club head origin positioned on the face plate at a geometric center of the face plate, the head origin including an x-axis tangential to the face plate and generally parallel to the ground when the head is ideally positioned, andwherein the head includes a golf club head center of gravity having an x-axis generally parallel to the origin x-axis, and wherein a golf club head moment of inertia about the head center of gravity x-axis divided by the golf club head mass without the at least one weight is between about 800 mm2 and about 4,000 mm2, and wherein at least one rib is attached to at least one of the two or more weight ports.
