Callaway X Prototype Irons 4-PW ( 7pcs )

Meet the Callaway X Prototype Iron: A Japanese Masterpiece

Get ready for something special—Callaway has just dropped the X Prototype Iron, and it's shaking things up in the world of premium irons. Made in Japan, this combo set is the ultimate version of the already famous "X FORGED Iron," but with some serious upgrades in feel and performance. If you thought the 2024 X FORGED Iron was impressive, the X Prototype takes it to a whole new level. We're talking about a perfect blend of cavity back, half cavity, and muscle back irons that are crafted for the pros and serious golfers.

Precision Meets Soft Feel—Made in Japan

This set is made using a unique process that involves a single forging hit with CNC milling. The result? A head that feels buttery soft and looks razor-sharp. It’s the kind of iron that advanced golfers will appreciate when they address the ball. Plus, it’s got a Tri-Level sole design that helps it glide through the turf like a hot knife through butter.

Why the Combo Set is a Game Changer

What makes the X Prototype Iron stand out is its combo setup. The I#4 and I#5 irons are cavity backs, perfect for giving you some extra forgiveness. Then, the I#6 and I#7 irons shift to a half cavity design for a nice mix of control and feedback. Finally, the I#8, I#9, and PW are pure muscle backs, giving you that solid feel and dead-on precision when you need it most. It’s a well-rounded setup that gives you a little bit of everything.

Next-Level Forging Process

Unlike most forged irons that go through multiple strikes, the X Prototype is forged with a massive 600 tons of pressure—just once! Then it’s milled down to its final shape. The fewer strikes keep the carbon steel super soft, giving you that perfect, smooth feel at impact. And since they’re CNC milled, there’s almost no variation between the clubs. Consistency is key, right?

Sleek and Sharp for Advanced Golfers

At address, the X Prototype looks sleek and sharp, with less offset than the X FORGED Iron. It’s got that thinner top blade that better players love, and it just screams “pro-level gear.” If you want a set that looks as good as it performs, this is it.

Smooth Turf Interaction with Tri-Level Sole

Like the X FORGED, this set features the Tri-Level sole design, but Callaway tweaked it a bit for the X Prototype. Both the leading and trailing edges are chamfered, helping the club cut through the turf with ease. That means better control and more consistent strikes, even from tricky lies.
