The Mizuno Pro 243 is a manufacturing masterpiece – more compact and precise than its predecessor, yet faster from the face and more satisfying at impact.

Improvements in performance only made possible through the long-term relationship between Mizuno’s R&D team and its exclusive Grain Flow Forging plant in Hiroshima, Japan.


Mizuno Pro 243-Iron Set (4-PW)

Excluding GST/HST

Grain Flow Forged HD in Hiroshima, Japan: From a single billet at Mizuno's exclusive facility - where Mizuno irons have been produced since 1968.


4120 Chromoly with Flow Microslot (4-7 iron): A wider, longer micro-slot to create a more expansive high energy area of clubface – resulting in a higher flight and faster ball speeds.


1025E Pure Select Mild Carbon Steel 8-GW: Solid feel and control where most needed, with modern lofts to maintain even distance gapping through the set


Soft Copper Underlay: A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of our Grain Flow Forged heads.


Wrap Around Sole Grind: Heavy relief around the sole for improved turf interaction and seamless transition from micro slot 7 iron into traditional 8 iron construction.


Exceptionally Compact Players Profile: Dramatically reduced topline and blade length throughout the set.


Increased bounce angle: Increased by a degree in the long irons and 2 degrees in the scoring irons – for improved turf interaction.


Full Satin Brush: A less reflective, modern finish.
