Abstract:
1. A golf club head, comprising: a body defining an interior cavity and comprising a sole including at least one weight port positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown, wherein the body has a forward portion and a rearward portion; and a face positioned at the forward portion of the body, the face having an ideal impact location defining a golf club head origin, the head origin including an x-axis tangential to the face 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 perpendicular to both the x-axis and y-axis; wherein the golf club head has a moment of inertia about a golf club head center of gravity z-axis generally parallel to the head origin z-axis greater than approximately 500 kg·mm wherein the ratio of a moment of inertia about a golf club head center of gravity x-axis generally parallel to the origin x-axis to the moment of inertia about the golf club head center of gravity z-axis is greater than approximately 0.8; and at least first and second mass elements formed in the body, the first mass element having a mass between approximately 3 g and approximately 23 g, and the second mass element having a mass between approximately 25 g and approximately 35 g, wherein: the first mass element has a head origin x-axis coordinate between about 35 mm and about 65 mm, a head origin y-axis coordinate between about 0 mm and about 30 mm, and a head origin z-axis coordinate between about −20 mm and about 10 mm; and the second mass element has a head origin x-axis coordinate between about −20 mm and about 10 mm, a head origin y-axis coordinate between about 90 mm and about 120 mm, and a head origin z-axis coordinate between about −20 mm and about 10 mm.
