Abstract: A golf club head includes a body having a crown opposite a sole, a toe end opposite a heel end, a back end, and a hosel. The golf club head also includes a club face having a loft below a loft threshold in which increasing a coefficient of friction between a golf ball and the club face decreases the spin imparted on the golf ball after impact with the club face. A surface feature positioned on a portion of the club face is configured to increase the coefficient of friction between the golf ball and the club face.
