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.

Srixon's new i-FORGED process starts with finding the IDEAL STEEL

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.

Then it takes CONDENSED FORGING.

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.

Lastly, HEAT SOFTENING

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.

ZXi7 features

• i-FORGED: proprietary condensed forging inserts that add strength in the hosel area, which allows for the use of new, softer S15C steel in the single-piece iron body for unprecedented feel and control. Added tungsten weighting perfects CG placement for ideal performance.

• PUREFRAME: This generation of PureFrame uses a larger forged ridge in the body of the Iron just behind the sweet spot. We've expanded this ridge for even better feel, stability, and control.

• Tour V.T. Sole: Prized by tour pros, Tour V.T. Sole's unique combination of leading-edge bounce plus trailing-edge relief means that, no matter how steep your downswing, you'll glide through turf to compress the ball with full power.

• Progressive Grooves: The 3i-7i features 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.

• Players Iron Shape: A thin topline, narrow sole, short blade, and minimal offset-the preferred look for tour-level and low-handicap golfers. These compact players irons feature a muscle-back cavity for maximum workability and a razor-sharp look.

SPECS

*The set is built at standard loft, length, lie, and grip.
