The Callaway Mack Daddy 4 wedge combines innovative performance technologies with premium components for optimum performance. After receiving extensive input from Tour players, industry legend Roger Cleveland used the feedback to create Tour refining shapes, soles, grinds and camber to give the MD4 wedges a more compact shape, straighter leading edge, tighter leading-edge radius and slightly more offset than the MD3 wedges. Callaway’s proprietary Groove-In-Groove Technology and Micro-Positive surface texture enhance spin and control while the combination of soft carbon steel, precise CG locations and crisp turf interaction provide a pure feel. The premium black matte finish is durable and Tour-inspired. The C Grind is ideal for medium-to- shallow attack angles and/or firm course conditions. The Increased relief, especially at the heel, makes it easier to play shots with the face open. Please note: Mack Daddy 4 Raw wedges are raw. With time and use, your Raw wedges will rust.
