i-FORGED

The i-FORGED technology uses condensed forging that extends from the high-toe area along the topline of the iron blade. This design enhances the overall strength, durability, and feel of the club. In addition, the forged faces on the ZXi5 have been softened to further improve the already exceptional feel at impact.

MAINFRAME iQ

MainFrame iQ features a variable-thickness network of grooves, channels, and notches that are precision-milled into the back of every ZXi5, ZXiU, and ZXU Utility Iron face. This advanced face design maximizes energy transfer at impact, resulting in increased ball speed, more consistent performance, and greater distance across the entire clubface.

TOUR V.T. SOLE

Srixon's Tour V.T. Sole technology refines turf interaction through a proprietary combination of sole widths, bounce angles, and notches. This carefully engineered design promotes smoother movement through the turf and helps maintain clubhead speed, even when contact occurs slightly behind the ball.

PROGRESSIVE GROOVES

The Progressive Grooves design features wider grooves on the 3i through 7i to optimize performance on longer shots in all playing conditions. The 8i through SW use deeper and closer-set grooves to improve spin control and debris management on approach shots. Laser milling between each groove further enhances friction and control in all weather conditions.

REFINED PLAYERS SHAPING

Developed with input from Srixon’s tour staff, the new ZXi Iron profile has been refined to create a cleaner and more precise appearance at address. The updated design also features a slightly thinner topline than the previous generation, giving players a more compact and confidence-inspiring look.

PRECISION FORGING BY ENDO

Every ZXi Iron face and body is forged at Endo, Japan’s premier forging facility and one of the most respected names in golf club manufacturing. Known as the gold standard in iron forging, Endo's craftsmanship ensures exceptional quality, consistency, and feel without compromise.
