1. A wood-type golf club head comprising:
a body comprising a face positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and having a crown surface area, and a skirt positioned around a periphery of the golf club head between the sole and crown;
wherein the head has a face center positioned on the face at an approximate geometric center of the face, the face center including a head origin x-axis tangential to the face and generally parallel to the ground when the head is ideally positioned, a head origin y-axis generally perpendicular to the head origin x-axis and generally parallel to the ground when the head is ideally positioned, and a head origin z-axis generally perpendicular to the head origin x-axis and to the head origin y-axis and generally perpendicular to the ground when the head is ideally positioned, the head having a center of gravity whose location is defined relative to the head origin x-axis via a CGx coordinate, the head origin y-axis via a CGy coordinate of no more than 50 mm, and the head origin z-axis via a CGz coordinate; and
a rear weight assembly releasably attached to the body and having a mass element and a screw at least partially contained in a rear weight port having a threaded portion defining a rear radial axis having a rear axis angle of 100-170 degrees from the head origin z-axis measured in a head origin y-z plane, wherein the rear radial axis passes through the face, and the rear weight assembly has a rear mass of 5-50 grams, a rear weight center of gravity establishing a rear weight head origin x-axis coordinate, a rear weight head origin y-axis coordinate of 80-130 mm, and a rear weight head origin z-axis coordinate of −10 mm to −30 mm;
wherein the head has an Ixx moment of inertia about a CG x-axis, and an Izz moment of inertia about a CG z-axis of 480-600 kg·mm2;
wherein the crown has a crown areal weight between about 0.15 g/cm2 and about 0.45 g/cm2 over at least 50% of the crown surface area; and
wherein the club head has an aspect ratio that is 0.45-0.58 and a coefficient of restitution greater than 0.8.
