Abstract: Described herein is a golf club head that includes a body that includes a sole portion, a crown portion, a skirt portion, a forward region, and a rearward region. The golf club head also includes a face portion including a striking face with a maximum height from the ground plane of at least about 50 mm. The golf club head has a peak crown height, from the ground plane, of at least about 60 mm. A volume of the golf club head is at least about 370 cm3. A location of a center-of-gravity of the golf club head is at a minimum distance (Zup) away from the ground plane. The difference between Zup and half of the peak crown height is less than about ?5.75 mm. A z-axis moment of inertia of the golf club head about a CG z-axis is greater than about 300 kg-mm2.

Abstract: Disclosed herein is a golf club head comprising at least one crown opening and at least one crown insert attached to the body and covering the at least one crown opening. The golf club head further comprises at least one sole opening and at least one sole insert attached to the body and covering the at least one sole opening. The golf club head additionally includes at least one weight member configured to clamp first and second ledges at selected locations along a sliding weight track. The golf club head also comprise a coefficient of restitution (COR) feature located on the sole of the golf club head. The at least one crown insert is formed from a composite material having a density between 1 g/cc and 2 g/cc. The at least one sole insert is formed from a composite material having a density between 1 g/cc and 2 g/cc.
