Mizuno Expands Pro Iron Line With New Modern Series

Last year, Mizuno flipped the script on its Pro Series with the release of the Pro S-1 and Pro S-3 irons. Clubs purposely designed with limited technology and positioned to be around for much longer than the now traditional 2-year product cycles for most irons.

Mizuno is one of the few equipment companies willing to admit there are limited advancements to be made to single-piece forged irons beyond looks, lofts, and (very importantly) sole designs. But, for those who are looking for more speed and forgiveness in their irons, this is where the new Modern (M, for short) series comes in.

Welcome To The Modern Series

The new Modern Series features two new irons plus a new driving iron incorporating multiple firsts for Mizuno, along with some tweaked materials engineering to build modern combo sets utilizing multiple metals to deliver performance.

All three irons in the M-series also feature updated sole designs, with the M13 having the same Triple Cut sole and the S-line, with more leading edge bounce and camber to allow the club to dig less through the turf.

Mizuno M-13

The M13 provides a smaller tour-proven shape with added technology in the mid and long irons to improve gapping, distance control, and launch angle consistency, not to mention something Mizuno has avoided in the S-line: stronger lofts.

The 4-5 irons have a Grain Flow Forged 4120 Chromoly face, topline, and hosel, along with a stainless back plate.

The 6-8 irons utilize a fully forged head made from 4115 Chromoly, while also incorporating Mizuno's Micro-slot technology to generate more compliance (flex) on the bottom of the face to produce faster ball speeds around a larger area.

The 9-Gap wedge short irons are made from a single piece of forged 1025E steel (the same steel used in the S-line heads) to deliver pure feedback and precision into the shorter irons.

Mizuno M-15

When it comes to Mizuno irons, the M-15s are a whole new animal in the Mizuno lineup, and in some ways are a combination of their previous best players' distance irons (245) and their players irons (243).

These hollow irons are shaped to offer sharp, modern lines in an iron packed with hollow body technology.

The 4-7 irons are constructed with a Grain Flow Forged HD 4135+ Chromoly hosel and face, so there is no weld separating the striking surface (face) from the player's connection to the shaft. The back of the iron is stainless steel and features strategically placed tungsten to precisely locate the center of gravity and add forgiveness.

The 8 iron works as a technology transition between the long and short irons and features the same construction as the longer irons, but without using tungsten.

As for the short irons, the 9-Gap wedge is built for pure feedback and control with the face and hosel made from 1025E steel with a stainless back plate to complete the partially hollow design.

Mizuno Pro Fli-Hi

In the category of driving irons, the Mizuno Fli-Hi is like a Mercedes AMG Wagon. Of course, it looks sleek from the outside, but on the inside is where it hides even more power. It's also one of the top models in use on the PGA Tour.

The newest Fli-Hi features a hollow body construction made from Mizuno's nickel chromoly 4335+ steel that has been heat treated for extra strength and flexibility - including a fully customizable bendable hosel.

Inside hides a 26 grams of tungsten, positioned to increase launch compared to traditional long irons, and a new offset face weld that allows for a thinner topline.

Price and Availability

The new M-15 and M-15 irons are priced at $215 per club, while the Fli-Hi is priced at $270.

All three models are available for fittings and presale starting on January 19th, with product hitting store shelves on February 5th.
