Key Technology Highlights:
Modern Series Forged Performance
The Mizuno Pro M-Series represents a fresh evolution in forged iron design, sitting alongside the Signature Series (S-1 and S-3). Built for modern golfers seeking added speed and forgiveness, both models maintain the craftsmanship, feel, and precision that define Mizuno Pro irons.
M-13 Integrated Construction (Tour-Preferred Profile)
The M-13 delivers a faster, more consistent flight with tour-inspired shaping.
• 4–5 irons feature Grain Flow Forged HD 4120 Chromoly faces with integrated CORAREA technology for increased ball speed.
• 6–8 irons utilize full-body Grain Flow Forged HD 4115 Chromoly with Micro-Slot Technology for added speed and consistency.
• 9–GW are one-piece Grain Flow Forged HD 1025 Elite Steel for unmatched feel and control in the scoring clubs.
M-15 Integrated Construction (High Launch & Forgiveness)
The M-15 is designed for higher launch and increased forgiveness while blending seamlessly through the set.
• 4–7 irons feature hollow-body Grain Flow Forged HD 4135+ Chromoly construction with tungsten weighting for stability and speed.
• 8 iron uses hollow-body construction for a smoother transition.
• 9–GW utilizes a partial hollow-body design for precision and improved feel.
Triple Cut Sole Design
Both models feature Mizuno’s Triple Cut Sole, with a beveled leading edge for clean turf entry and a trailing edge bevel that reduces drag—promoting consistent contact from fairway, rough, and tight lies.
Whether you’re a skilled ball striker looking for modern speed (M-13) or a player seeking higher launch and added forgiveness without sacrificing forged feel (M-15), the Mizuno Pro M-Series irons deliver tour-level craftsmanship with modern performance.
