Abstract
A golf club head includes a body defining an interior cavity. The body includes 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. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. The face defines a striking surface having an ideal impact location at a golf club head origin. Some embodiments of the club head form a club head for a fairway wood that has a high moment of inertia, a low center-of-gravity and a thin crown.
