1. A golf club head comprising:
a body 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 the crown, wherein at least a portion of the sole, a portion of the crown and a portion of the skirt are formed of a same material, 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, wherein a face plane is defined to extend tangential to the ideal impact location; wherein the body extends a distance L transversely away from the face plane and defines cross-sectional areas A along planes parallel to the face plane and spaced rearward from the face plane by a distance q, wherein a body region is defined between a dimension of q/L of about 0.05 to a dimension of q/L of about 1.0, and wherein within the body region at least about 50% of the cross-sectional areas A are between an upper cross-sectional area limit Au and a lower cross-sectional area limit Al, where
Au=5512(q/L)2−1.4026(q/L)+8875+1200(q/L)+500, and (1)Al=5512(q/L)2−14026(q/L)+8875−2000[1−(q/L)]2−300; (2) wherein the golf club head has a head origin defined as a position on the face plane at a geometric center of the face, the head origin including an x-axis tangential to the face and generally parallel to the ground when the head is ideally positioned where a positive x-axis extends towards the heel portion, a y-axis extending perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned where a positive y-axis extends from the face and through the rearward portion of the body, and a z-axis extending perpendicular to the ground, to the x-axis and to the y-axis when the head is ideally positioned where a positive z-axis extends from the origin and generally upward, wherein the golf club head has a center of gravity with an x-axis coordinate between approximately −5 mm and approximately 10 mm, a y-axis coordinate between approximately 20 mm and approximately 50 mm, and a z-axis coordinate between approximately −10 mm and approximately 5 mm. |
