A favorite on tour, the hollow-bodied Srixon ZXiU Utility Irons are designed as a potent long iron replacement, delivering increased power, forgiveness, and control to the top end of your bag. Feel is and has always been a priority for Srixon, and the ZXiU's new i-FORGED construction improves upon the company's already exceptional impact sensation. Consisting of a Condensed Forging process that stretches from the high toe area and along the topline of the blade, this technique enhances the iron's strength and durability, allowing for the usage of a softer-feeling face material without sacrificing performance. Srixon utilizes artificial intelligence to strategically mill a network of grooves, channels, and cavities into the back of the ZXiU's face. This variable thickness pattern, called MainFrame, vastly improves COR and forgiveness by maximizing the face's capacity to flex, resulting in explosive ball speed on center strikes and preserved speed on mishits. As an added benefit, removing mass from the face bolsters the cavity back's perimeter-weighted design, yielding additional MOI and stability. The ZXiU marks the first time Srixon's utility offering receives their outstanding Tour V.T. Sole. This unique combination of sole widths, bounce angles, and notches encourages smooth turf interaction, an essential factor in consistent ball striking. Srixon finishes the ZXiU with Mitsubishi's graphite MMT shaft and Golf Pride's Tour Velvet 360 grip.� Srixon ZXiU Utility Irons Feature: Forgiving hollow-body long irons with Srixon's widest soles and minimal offset i-FORGED Condensed Forging improves strength and durability, allowing for a softened forged face that offers exceptional feel MainFrame network of milled channels behind the face amplifies ball speed, adds forgiveness, and saves weight for increased MOI (stability) Tour V.T.
