ZX4 MKII 4-PW Iron Set with Steel Shafts

Product Overview: ZX4 Mk II Irons present game improvement forgiveness for mid- to high- handicap players. Behind the Irons' sleek address looks and premium forged feel is maximum forgiveness plus powerful distance. And it's all thanks to a hollow head design with extra-strong lofts. Featuring a narrow topline, moderate sole width, our longest blade length, and our highest offset. Features: MAINFRAME MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4 Mk II, ZX5 Mk II, and ZX Mk II Utility Iron faces that maximizes flex at impact. MainFrame not only boosts COR, it also repositions mass away from the face and into the toe and sole for a lower Center of Gravity. This creates more than just faster ball speed, but also more consistency and forgiveness, enhancing all aspects of your Iron play, shot for shot. TOUR V.T. SOLE Our dynamic Tour V.T. Sole helps maintain clubhead speed through impact for clean strikes across fairway, rough and sand—even if you contact the turf slightly behind the ball. A higher bounce on the leading edge prevents digging; then, a lower bounce on the trailing edge curves away from the turf, so you can still manipulate face angle for maximum workability. PROGRESSIVE GROOVES The 4i–7i feature wide grooves, ideal for longer shots in all conditions. The 8i–AW have deeper, closer set grooves which cut through grass and debris to enhance spin on approach shots. Laser milling between each groove, on every loft, enhances friction in all conditions.
