LIMITED EDITION BLACK CHROME IRONS & TOUR-INSPIRED ESSENTIALS

We've spent decades in pursuit of the best-feeling Irons possible. i-FORGED, or Impact Forged, is our latest step in that journey. It's an array of our greatest innovations in Iron metallurgy to date, cementing our worldwide leadership as forging technologists.

What's the softest steel we've ever used to make an Iron? S15C, which makes ZXi7 7% softer. ZXi5 and ZXiU face plates are also 14% softer. And ZXi4 now features the softer SUS17-47 for its body material.

Using softer steels enhances ZXi feel. But strength matters, too. To deliver both, we use Condensed Forging. Here's how it works:

The hydraulic dies which forge red-hot billets into ZXi Irons imprint an array of raised features onto each rough Iron shape. A second forge condenses those protrusions back into the clubhead, placing strength in those precise locations without sacrificing overall feel.

* Condensed Forging featured on ZXi7, ZXi5, and ZXiU Irons.

Because Condensed Forging adds localized strength right where we need it, we have the freedom to re-optimize the temperature of our heat-treating ovens and produce our softest treatments yet.

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 ZXi5 are softened to improve this already exceptional feel. Added tungsten weighting perfects CG placement for ideal performance.

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.

Our Tour V.T. Sole's proprietary combination of sole widths, bounce angles, and notches ensures a smooth glide through fairway, rough, and sand without any loss of speed.

The 3i-7i feature wider grooves, while the 8i-AW have deeper, closer-set grooves, to ensure consistent spin across the set. Laser milling between each groove, on every loft, adds bite on every strike.

ZXi5 features a slightly wider sole with moderate blade length and offset, giving attuned golfers enhanced distance, forgiveness, and workability—all with an ultra-clean look at address.

† To match USGA and R&A Industry guidelines, Srixon has modified how club lengths are measured and published. Our published length specifications are now approximately ¼" longer for Irons. Note: The actual length of the Irons has not changed, only how they are measured.
