1. A golf club head, comprising:
- a body defining an interior cavity, a sole portion positioned at a bottom portion of the golf club head, a crown portion positioned at a top portion, and a skirt portion positioned around a periphery between the sole and crown, the body also having a forward portion and a rearward portion, and a face positioned at the forward portion of the body, the face having a thickness no greater than 2.5 mm,wherein the body has a volume greater than 250 cm3,wherein the face has a static loft angle of 12-19 degrees,wherein the golf club head has a center of gravity that is 7-20 mm below the geometric center of the face of the golf club head as measured along a z-axis of the golf club head having an origin at the geometric center,wherein a projection of the center of gravity is located on the face and at an elevation below the geometric center of the face,wherein the golf club head has a Delta 1 value of less than or equal to 25 mm,wherein a first portion of the body located above the geometric center of the face is formed of a non-metallic material having a non-metallic material density and a first portion thickness of less than 0.7 mm,wherein a second portion of the body located below the geometric center of the face is formed of a metallic material having a metallic material density that is at least twice the non-metallic material density, andwherein at least a portion of the sole portion is formed of the metallic material and has a sole thickness that is at least twice the first portion thickness.

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. Embodiments include golf club heads having high static loft angles, low centers of gravity, or both high static loft angles and low centers of gravity.

13. A golf club head, comprising:
-
a club head body having an external surface with a heel portion, a toe portion, a crown, a sole, and a ball striking face having a thickness no greater than 5.0 mm, wherein the wherein the body has a volume greater than 250 cm3 and the ball striking face has a static loft angle of 13-18 degrees, wherein the ball striking face of the club head body has a geometric center, wherein the golf club head has a center of gravity that is 7-20 mm below the geometric center of the face of the golf club head as measured along a z-axis of the golf club head having an origin at the geometric center, wherein the golf club head has a Delta 1 value of 10-25 mm, and wherein the club head body has a center of gravity whose projection onto the ball striking face of the club head body is located off-center from the geometric center in a direction toward the sole, the golf club head has a roll radius of 300 mm or greater, and the golf club head has a moment of inertia about a golf club head center-of-gravity x-axis, Ixx, of 150-500 kg-mm2. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
