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.

• 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.
• Soft Copper Underlay:  A microlayer of copper beneath Nickel Chrome – an additional touch to enhance the sensational feel of our Grain Flow Forged heads.
• 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.
• Harmonic Impact Technology: Applied to closely match the vibration patterns identified with a soft muscle-back feel.
• 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.
