First Claim
1. A golf club head comprising:
- a club head body having a crown, a sole, a heel, and a toe;
a face portion connected to a front end of the club head body, the face portion including a geometric center defining an origin of a coordinate system when the golf club head is in a normal address position; and

wherein in a y-z plane passing through the origin the crown height continuously increases starting from the face-to-crown transition up to a local maximum;
wherein a CG effectiveness product (CGeff) for the golf club head is defined as CGeff=CGy×
Δ
z and the CGeff is at least 806 mm2; and
wherein the golf club head further comprises a sole feature, the sole feature comprising an extended platform formed in the sole, the extended platform extending rearwardly from a first end to a second end, and further comprising;
a planar sole surface and opposed sloped portions that, when the golf club head is in a normal address position, slope away from the ground plane toward the crown, the opposed sloped portions comprising a sloped heel side portion positioned heelward of the planar sole surface and a sloped toe side portion positioned toeward of the planar sole surface;
a forward portion adjacent the first end; and
a rearward portion adjacent the second end,wherein the extended platform has a first center point positioned at the first end and a second center point positioned at the second end, andwherein the second center point is positioned toeward of the first center point and toeward of the y-axis.

Abstract
A golf club head includes a club body including a crown, a sole, a skirt disposed between and connecting the crown and the sole and a face portion connected to a front end of the club body. The face portion includes a geometric center defining the origin of a coordinate system when the golf club head is ideally positioned, the coordinate system including an x-axis being tangent to the face portion at the origin and parallel to a ground plane, a y-axis intersecting the origin being parallel to the ground plane and orthogonal to the x-axis, and a z-axis intersecting the origin being orthogonal to both the x-axis and the y-axis. The golf club head defines a center of gravity CG, the CG being a distance CGY from the origin as measured along the y-axis and a distance CGZ from the origin as measured along the z-axis.
