Srixon ZXi5+ Irons 2026

The Srixon ZXi5+ is a fully forged, hollow-body players' distance iron built for golfers who want more distance and forgiveness in a tour-authentic package. A forged Sup10 steel face is paired with a forged S20C body and tungsten weighting through the long and mid irons, blending explosive speed with the clean looks and soft feel of a premium forged iron.

Srixon's i-FORGED process combines condensed forging with a controlled heat-softening step: extra material is concentrated in high-stress zones around the high toe and topline for strength, while the rest of the head is heat-treated for a softer, more responsive feel. Behind the face, MainFrame iQ mills a variable-thickness network of grooves, channels, and notches that trims face mass by up to eight percent — weight that's redistributed to lower the CG and raise MOI for faster ball speeds and greater stability.

A model-specific Tour V.T. Sole tunes width, bounce, and notching to keep the head moving cleanly through any surface without losing speed on off-center strikes, while Progressive Grooves — wider through the long irons, deeper and tighter in the scoring clubs, with laser milling between each groove — hold spin consistent across the set. Compared to the standard ZXi5, the ZXi5+ runs a slightly longer blade and wider sole for even more forgiveness and stronger, more penetrating ball flight.
