Golf club head
A high forgiveness wood-type golf club head comprises a body and a face. The body comprises a sole that forms a bottom portion of the golf club head, a crown that forms a top portion of the golf club head and a skirt that forms a periphery of the golf club head between the sole and the crown. The face place is positioned at a front portion of the golf club head opposite a rear portion of the golf club head. The body defines an outer periphery having a generally triangular shape in plan.
