1. A golf club head, comprising:
a body defining an interior cavity and comprising a sole 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 ratio of a moment of inertia about a golf club head center of gravity x-axis generally parallel to the head origin x-axis to a moment of inertia about a golf club head center of gravity z-axis generally parallel to the head origin z-axis is greater than approximately 0.6; at least one mass element permanently secured to or integrally formed in the body proximate to the face and having a mass between approximately 3 g and approximately 23 g, wherein the at least one mass element has 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. |
