Mizuno Pro Line Arrives For 2026

Evolution of an Icon: Introducing the Mizuno Pro Modern Series

There is a saying in golf that few brands can claim to own: "Nothing feels like a Mizuno."

For decades, that feeling - the soft, solid sensation of a grain flow forged iron - has been the benchmark for elite ball strikers. But the modern game demands more than just feel. Players want speed, forgiveness, and optimized launch windows.

Enter the Mizuno Pro Modern Series.

Comprising the new M-13 and M-15 models and the Fli-Hi, this release sits alongside the traditional Signature Series (S-1 and S-3) but represents a distinct evolution. It's where Mizuno’s legendary craftsmanship meets next-generation speed.

Here is what you need to know about the new options arriving at The Clubroom.

The M-13: Tour Precision, Accelerated

Replacing the popular Mizuno Pro 243, the M-13 is designed for the ball striker who refuses to compromise on looks but needs modern ball speeds.

The magic here is in the progression. The long irons (4 & 5) utilize a sophisticated Pocket Cavity construction, allowing for a face that is significantly thinner than its predecessor for increased distance. As you move into the mid-irons, the design shifts to a Micro-Slot construction for controlled speed, before transitioning into a pure, one-piece forging in the scoring clubs (9-GW).

You get a set that looks like a classic tour iron at address but performs with modern ferocity.

The M-15: The Ultimate Hollow Body Performance

Successor to the 245, the M-15 is a masterpiece of hidden engineering. It offers the most playable performance in the Mizuno Pro line while maintaining a sleek, tour-informed profile.

The M-15 features a hollow body design with massive tungsten weighting suspended within the head to improve launch stability without sacrificing the "Mizuno feel." It creates a seamless transition from the high-power Chromoly long irons into the precision-focused short irons.

If you are looking for a blade-like aesthetic that offers genuine help on off-center strikes, the M-15 is the new standard.

The Mizuno Pro Fli-Hi

Trusted by tour players around the world, this is an easy launching and powerful long iron replacement. It's an ideal flow into the new M13 or M15 iron set. 

It's available in 2 (16.5°), 3 (19°) or 4 (21.5°) and the team can help dial in the specifications for your game.

  • INTERNAL TUNGSTEN WEIGHTING: 26 grams of weight low in the head for elevated launch compared to traditional long irons.

  • OFFSET FACE WELD: Placing the weld line inside the upper face-gauge allowed a thinner topline. On the bottom edge, the weld line is back from the face, allowing greater flex and ball speeds from low on the face.

  • HARMONIC IMPACT TECHNOLOGY: Applied to best match the vibration patterns Mizuno’s tour players identified with a soft muscle-back feel.

Experience the Modern Series

Reading about the technology is one thing; feeling the compression of a Grain Flow Forged head is another.

These irons are precision instruments. To get the performance Mizuno engineers intended, they need to be paired with the right shaft and lie angle for your swing.

The M-13 and M-15 along with the Fli-Hi are available for testing later this month. Come in, see how they sit behind the ball, and let the data show you what the Modern Series can do for your game.
