The M-15, successor to the Mizuno Pro 245, offers a fully integrated progression of performance from long iron to wedge. Each section of the set is designed with a specific purpose, creating smooth transitions in both shape and feel throughout.

Suspended Tungsten Weighting

To enhance launch and stability, 51g of tungsten in the long irons and 50.3g in the mid irons is strategically suspended within the head. This precise weighting increases forgiveness and promotes straighter ball flights without compromising compact shaping.

Multi-Material Hollow Construction (4–8 Iron)

Long and mid irons combine a Grain Flow Forged 4135+ Chromoly face and neck with a stainless steel back piece, increasing rebound efficiency and supporting higher ball speeds across the hollow construction.

Partial Hollow 1025E Forging (9–GW)

From 9-iron to gap wedge, the M-15 transitions into a partial hollow Grain Flow Forged 1025E HD body with a stainless steel back. This construction prioritises precision, trajectory control and manoeuvrability in the scoring clubs.

Contoured Ellipse Face with CORTECH (4–8 Iron)

The 4–8 irons are defined by the Contoured Ellipse Face, the latest evolution of Mizuno’s CORTECH technology. This multi-thickness forged face is paired with a hollow body construction to optimise ball speed and consistency while maintaining a soft, responsive impact feel.

Refined Sole Geometry

Refined sole shaping with added bounce promotes cleaner turf entry and smoother exit, supporting consistent contact and performance across varying lies and course conditions
