ZXiU Utility Irons are potent long Iron replacements-even among tour pros-with elevated power, control, and forgiveness in a blade-like design with minimal offset. i-FORGED Condensed Forging stretching from the high-toe area and along the topline of the Iron blade enhances overall strength, durability, and feel. Then the forged faces on ZXiU are softened to improve this already exceptional feel. 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 For the first time ever, Srixon's included Tour V.T. Sole on all ZXiU Utility Irons, along with a leading-edge side chamfer. This proprietary combination of sole widths, bounce angles, and notches encourages a smooth glide through the turf without losing speed. UTILITY IRON SHAPING Srixon's widest soles, combined with minimal offset and an appealing look at address, makes the forgiving, hollow ZXiU Utility long Irons professional favorites.
