i-FORGED CONSTRUCTION ZXi4 Irons feature a softer SUS17-47 material, which delivers dramatically better feel than previous generations of ZX4 Irons. This softer material allows us to adjust loft and lie more easily to ensure the perfect fit. MAINFRAME MainFrame saves additional weight and adds more MOI through an enhanced network of milled channels on the back side of the Iron face. At impact, this system amplifies ball speed and adds forgiveness. TOUR V.T. SOLE Our Tour V.T. Sole’s proprietary combination of sole widths, bounce angles, and notches ensures a smooth glide through fairway, rough, and sand without any loss of speed. PROGRESSIVE GROOVES The 4i-7i feature wider grooves, while the 8i-SW have deeper, closer-set grooves, to ensure consistent spin across the set. Laser milling between each groove, on every loft, adds bite on every strikes. PLAYERS-INSPIRED SHAPE ZXi4’s unique hollow design features moderate sole width, our longest blade length, and our highest offset for max forgiveness, all while still offering an appealing look at address.
