Mizuno Pro M-15 Iron Set (PRO M15 STS)

Who’s It For?

Designed for golfers who want a smooth, confidence‑building progression from long iron to wedge, the Mizuno Pro M-15 Irons suit players seeking higher launch, added forgiveness, and a refined feel without giving up premium craftsmanship. The set is engineered so each section serves a specific purpose, creating seamless transitions in shape and performance, all while maintaining the forged heritage and precision that define the Mizuno Pro line.

The Tech Story

The Mizuno Pro M‑15 irons leverage a fully modernized forged design that blends speed, stability, and precision through an integrated multi‑material construction. A compact, tour‑inspired profile with a thin graduated top line delivers maneuverability and a consistent flight, while suspended tungsten weighting—51g in the long irons and 50.3g in the mids—enhances launch and forgiveness without sacrificing shape. The long and mid irons (4–8) feature a hollow body combining a Grain Flow Forged 4135+ Chromoly face with a stainless steel back to maximize rebound and ball speed, further boosted by the advanced Contoured Ellipse Face and CORTECH multi‑thickness geometry. In the scoring clubs (9–GW), the head transitions to a partial hollow Grain Flow Forged 1025E HD body for sharper control and refined trajectory management. Across the set, refined sole geometry improves turf interaction, while Harmonic Impact Technology and a copper underlay fine‑tune vibration for Mizuno’s signature soft-yet-solid feel. A premium Nickel Chrome Satin finish completes the M‑15’s contemporary performance‑driven design.
