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 strikeface at the head front portion and comprising a face height and a strikeface centerpoint, the face height being between 33 mm and 71 mm and the strikeface centerpoint positioned at a midpoint of the face height;

    a head volume of the golf club head is approximately 420 cc to approximately 470 cc;

    a head weight of the golf club head is approximately 185 grams to approximately 225 grams;

    a head center of gravity;

    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 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 28 mm to approximately 102 mm;

    the head body comprises a weight structure located towards the head sole portion and the head rear portion;

    a clock grid comprises at least;

    a 12 o'"'"'clock ray;

    a 3 o'"'"'clock ray;

    a 4 o'"'"'clock ray;

    a 5 o'"'"'clock ray;

    a 8 o'"'"'clock ray; and

    a 9 o'"'"'clock ray;

    when the golf club head is at the address position over the ground plane, from a bottom view of the golf club head, the 12 o'"'"'clock ray is aligned with the strikeface centerpoint and orthogonal to a front intersection line between the loft plane and the ground plane;

    the clock grid is centered along the 12 o'"'"'clock ray, at a midpoint between a front end of the head front portion and a rear end of the head rear portion;

    the 3 o'"'"'clock ray extends towards the head heel portion;

    the 9 o'"'"'clock ray extends towards the head toe portion;

    a perimeter of the weight structure is at least partially bounded between the 4 o'"'"'clock ray and the 9 o'"'"'clock ray; and

    a center of gravity of the weight structure is located between the 5 o'"'"'clock ray and the 8 o'"'"'clock ray.
