Golf club

A 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;
• at least one protrusion extending above a portion of the crown, wherein the at least one protrusion is located entirely forward of a center of gravity (CG) of the golf club head and proximate the face;
• wherein the at least one protrusion has a height measured in a direction parallel to the z-axis, a length measured in a direction parallel to the y-axis, and a width measured in a direction parallel to the x-axis;
• wherein the golf club head has a vertical CG location (Δz) positioned vertically below the origin as measured relative to the ground plane, and a y-axis CG location (Δy) positioned rearward of the protrusion;
• a removable shaft system configured to adjustably attach a golf club shaft to the golf club head, the removable shaft system comprising a sleeve configured to attach to the golf club shaft and a fastener to secure the sleeve to the golf club head;
• a rearward mass pad located within the interior cavity and positioned rearward of the CG of the golf club head proximate a rear portion of golf club head;
• and
• the rearward mass pad further including a threaded aperture configured to retain at least a portion of a weight.
