Srixon ZX4 MKII Mens Left Hand No. 7 Iron – Stiff Flex

MAIN FRAME

MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of the Iron face that maximizes flex at impact. This second-generation design goes even further, not just boosting COR but repositioning mass away from the face and into the toe and sole for a lower CG.
