1. A fairway wood type golf club head comprising:
- a golf club body defining an interior cavity including a sole, a crown connected to the sole by a skirt, and a hosel connected to at least one other feature of the golf club body;
a face connected to a front end of the golf club body, the face including a center of the face defining an origin of a reference coordinate system having an x-axis being tangent to the face and parallel to a ground plane when the golf club head is positioned at address, a y-axis being orthogonal to the x-axis and parallel to the ground plane, and a z-axis being orthogonal to both the x-axis and y-axis;
an extended face feature which expands an overall hitting area of the golf club head;
a coefficient of restitution feature (CORF) located in a forward portion of the sole proximate the face, wherein the coefficient of restitution feature is a slot;
a mass pad located on the sole within the interior cavity and positioned proximate the face in the forward portion of the sole, the mass pad being located rearward of the coefficient of restitution feature;
wherein the golf club head has a vertical CG location (Δ
z) positioned vertically below the origin as measured relative to the ground plane, and a y-axis CG location (Δ
y) positioned rearward of the coefficient of restitution feature as measured from the origin in a direction parallel to the y-axis;
wherein the extended face feature has a width as measured parallel to the x-axis ranging from 30 mm to 62 mm.

12. A fairway wood type golf club head comprising:
-
a golf club body defining an interior cavity including a sole, a crown connected to the sole by a skirt, and a hosel connected to at least one other feature of the golf club body; a face connected to a front end of the golf club body, the face including a center of the face defining an origin of a reference coordinate system having an x-axis being tangent to the face and parallel to a ground plane when the golf club head is positioned at address, a y-axis being orthogonal to the x-axis and parallel to the ground plane, and a z-axis being orthogonal to both the x-axis and y-axis; a coefficient of restitution feature (CORF) located in a forward portion of the sole proximate the face, wherein the coefficient of restitution feature is a slot; a mass pad located on the sole within the interior cavity and positioned proximate the face in the forward portion of the sole, the mass pad being located rearward of the coefficient of restitution feature; wherein the golf club head has a vertical CG location (Δ
z) positioned vertically below the origin as measured relative to the ground plane, and a y-axis CG location (Δ
y) positioned rearward of the coefficient of restitution feature as measured from the origin in a direction parallel to the y-axis;wherein a maximum height of the face as measured parallel to the z-axis from the ground plane is at least 90% of the maximum crown height as measured parallel to the z-axis from the ground plane; wherein the golf club head includes an extended face feature that extends about tangent to the face and defines a top end of the face, wherein the extended face feature expands an overall hitting area of the golf club head. - View Dependent Claims (13, 14, 15)

16. A fairway wood type golf club head comprising:
-
a face including a toe end, a heel end, a crown end, and a sole end; and a golf club head body defined by a crown and a sole, the crown joined to the sole by a skirt, wherein the golf club head body defining an interior cavity; the crown coupled to the crown end of the face; the sole coupled to the sole end of the face; a coefficient of restitution feature (CORF) located in a forward portion of the sole proximate the face, wherein the coefficient of restitution feature is a slot; wherein the golf club head has a vertical CG location (Δ
z) positioned vertically below the origin as measured relative to the ground plane, and a y-axis CG location (Δ
y) positioned rearward of the coefficient of restitution feature as measured from the origin in a direction parallel to the y-axis;wherein the golf club head having a head length from a leading edge to a trailing edge between 73 mm and 97 mm, a crown height as measured from the ground plane in a direction parallel to the z-axis, wherein a maximum crown height of the golf club head is between 30 mm to 44 mm, a loft of 15 degrees or greater, and a volume of up to 200 cc; the face including a geometric center that defines the origin of a coordinate system in which an x-axis is tangential to the face portion at a center of the face and is parallel to a ground plane when the golf club head is in a normal address position, a y-axis extending perpendicular to the x-axis and parallel to the ground plane, and a z-axis extending perpendicular to the ground plane, wherein a positive x-axis extends toward the toe end from the origin, a positive y-axis extends rearwardly from the origin, and a positive z-axis extends upwardly from the origin; wherein the golf club head includes an extended face feature that extends about tangent to the face and defines a top end of the face, wherein the extended face feature expands an overall hitting area of the golf club head; wherein the extended face feature has a width as measured parallel to the x-axis ranging from 30 mm to 62 mm. - View Dependent Claims (17, 18, 19, 20)
