Hollow Construction: The Srixon ZX4 irons feature a hollow construction in every loft to deliver shots that launch straight and stay on target.
MainFrame: A variable thickness pattern made up of grooves, channels, and cavities maximises ball speed and enhances distance.
Tour V.T. Sole: A V-shaped sole glides smoothly through the turf for improved feel and feedback.
Tungsten Weighting: High-density tungsten in the base of ZX4's long and mid irons lowers their centre of gravity to deliver high launching shots.
Face Forged: A forged HT1770 Steel face is strong and light, increasing face-flex at impact for enhanced speed while maintaining Srixon's signature iron feel.
