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, 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;

    at least a first weight port and a second weight port formed in the body;

    at least a first weight having a first weight mass between about 1 gram and about 18 grams and configured to be retained at least partially within the first weight port formed in the body; and

    at least a second weight having a second weight mass between about 1 gram and about 18 grams and configured to be retained at least partially within the second weight port formed in the body;

    wherein the head has a golf club head origin positioned on the face plate at an approximate 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, a y-axis generally perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned, and a z-axis generally perpendicular to the x-axis and to the y-axis, wherein a positive x-axis extends toward a club head heel, a positive y-axis extends toward the cavity, and a positive z-axis extends away from the ground with the head ideally positioned, andwherein the first weight has a head origin z-axis coordinate between about 5 mm and about 15 mm and a head origin x-axis coordinate between about 0 mm and about 20 mm, and the second weight has a head origin z-axis coordinate between about −

    30 mm and about −

    10 mm and a head origin x-axis coordinate between about 0 mm and about 20 mm, and a volume of the golf club head is between about 180 cm3 and about 600 cm3; and

    wherein a difference between the first weight mass and the second weight mass multiplied by a distance between the first weight and the second weight is between about 950 g-mm and about 14,250 g-mm.
