Advanced, 2-Pass micro milling pattern provides a strategically designed roughness close to the USGA limit. This leads to increased friction and more spin. especially from the rough and inconsistent lines.
TOUR ZIP GROOVES
Fourth generation Tour Zip Grooves feature steeper walls and sharper radii than ever before, Through testing we have seen that more grass, dirt and moisture are channeled away fromt he face for cleaner contact and more consistent spin.
Fine tunes the micro-roughness for more consistency and texture across the face. This allows us to reach the USGA roughless limit, and pushing the boundary lends itself to increased spin on pitch and chip shots.
