1. A golf club head comprising:
- a head body comprising;
a head front portion;
a head rear portion;
a head heel portion;
a head toe portion;
a head sole portion;
a head top portion; and
a hosel structure having a bore for receiving a golf club shaft, the bore having a hosel axis;
a face portion at the head front portion and comprising;
a strikeface centerpoint;
a strikeface perimeter; and
a face height bounded by the strikeface perimeter, the strikeface centerpoint positioned at a midpoint of the face height;
a head center of gravity; and
a weight structure located towards the sole portion and the rear portion of the head body, the weight structure having a weight center;
at least one of;
a first performance characteristic;
or a second performance characteristic;
a third performance characteristic;
wherein;
when the golf club head is at an address position over a ground plane;
a head vertical axis extends through the head center of gravity and is orthogonal to the ground plane; and
a head horizontal axis extends through the head center of gravity, and is orthogonal to the head vertical axis;
a loft plane of the golf club head is tangent to the strikeface centerpoint;
a front plane of the golf club head extends through the strikeface centerpoint, parallel to the hosel axis, and orthogonal to the ground plane;
a head depth plane extends through the strikeface centerpoint, parallel to the head horizontal axis and perpendicular to the loft plane;
a CG height axis extends through the head center of gravity and intersects the head depth plane perpendicularly at a first intersection point;
a head CG height of the head center of gravity is measured, along the CG height axis, between the head center of gravity and the first intersection point;
a head CG depth of the head center of gravity is measured, parallel to the ground plane and orthogonal to the front plane, between;
a second intersection point located at an intersection between the front plane and the ground plane; and
a third intersection point located at an intersection between the head vertical axis and the ground plane;
the head CG depth is approximately 25 mm to approximately 102 mm;
the face height is approximately 33 mm to approximately 71 mm, measured parallel to the loft plane;
the first performance characteristic comprises;
the head CG height being less than or equal to approximately 5.08 mm;
the second performance characteristic comprises;
a CG performance ratio of less than or equal to 0.56, as defined by (a) 76.2 mm minus the face height, divided by an absolute value of the head CG height;
the third performance characteristic comprises;
(a) the head volume magnitude added to (b) a ratio between the head CG depth divided by an absolute value of the head CG height;
wherein the third performance characteristic is greater than or equal to 425 cc.
