The ZXi5's new i-FORGED construction improves upon the Srixon'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 at no cost to performance.

Srixon utilizes artificial intelligence to strategically mill a network of grooves, channels, and cavities into the back of the ZXi5'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.
