When it comes to golf irons, what you see at address is only the beginning. Like an iceberg, the true story runs deep – and with the new Mizuno Pro Limited Edition Iceberg Iron Set, available now at Worldwide Golf, there’s more beneath the surface than meets the eye.

This exclusive combo set – just 1,000 released worldwide – is Mizuno at its most refined and expressive. It’s a cool nod to the brand’s iconic blue roots, sculpted from decades of forging tradition, and shaped by feedback from the game’s most exacting players. But make no mistake: the Iceberg isn’t just for display. It’s built to play.

A Deep Freeze of Forging Precision

Forged in Hiroshima, Japan, the Iceberg Irons are born from Grain Flow Forged HD technology, Mizuno’s signature process that turns 1025E Pure Select carbon steel into muscle. The result is an iron that delivers buttery feedback, shaped by Harmonic Impact Technology to ring true with every swing.

These are tools forged by time: with a copper underlay beneath the nickel chrome plating, the feel is rich, responsive, and unmistakably Mizuno. Concentrated mass sits directly behind the sweet spot, amplifying that signature sensation of a well-struck shot.

One Set, Two Stories

The Iceberg set follows a progressive blueprint built for complete performance:

• 3-6 Irons (Pro S-3 Cavity Backs) – Designed with a shallow cavity for added launch and forgiveness where it’s needed most.

• 7-PW (Pro S-1 Muscle Backs) – True muscle-back blades for maximum control and crisp feedback in your scoring clubs.

Visually, the set offers a flowing spectrum of blue – from glacial tones in the long irons to deeper hues in the wedges. It’s a subtle gradient that adds personality without compromising playability.

Designed with Tour Feedback

Mizuno’s tour team didn’t just test these irons – they helped shape them. The topline is thinner. The short irons are more compact. And the bounce has been increased across the set to improve turf interaction, especially in the scoring clubs.

From the aggressively tapered blade design to the six-times-tighter steel tolerances, every detail reflects the input of players who demand precision down to the millimeter.

Before They Melt

The Mizuno Pro Iceberg Irons are a limited-edition release with serious game – and serious appeal. Whether you’re stepping up to the tee or admiring the craftsmanship in hand, the irons invite you to dive deeper.
