Srixon ZX4 Iron
Hollow construction for exceptional forgiveness. Strong and lightweight forged HT1770 steel face offers increased face-flex for greater speed and distance. 431 steel body absorbs vibrations for a softer feel. Premium, high-density tungsten in base of long and mid irons lowers COG for a high-launch profile. MainFrame technology milled into the backside of the face features a variable thickness pattern that maximizes COR for greater ball speed and distance. Tour V.T. Sole offers smoother turf interaction and improved impact feel.
