Cleveland CG15 wedges feature a laser milled face to optimize face roughness & increase spin. Zip grooves are features in the CG15 wedges which are wider & deeper than standard grooves (legal until 2024) which also help increase spin for greater stopping power. An S sole gives you a wider sole near the heel & a narrower sole near the toe to help improve bunker play. A black pearl finish offers anti glare on sunny days & also a softer feel.
