Integrated ConstructionThe M-15 features a compact, manoeuvrable head shape with a thin, progressively graduated topline across the set. Tour-preferred proportions combine with a modern construction approach to deliver a faster, more consistent flight profile without sacrificing control or feel.Suspended Tungsten WeightingTo enhance launch and stability, substantial tungsten weighting is precisely suspended within the head. The long irons utilise 51g of tungsten, while the mid irons feature 50.3g, positioning mass low and deep to increase forgiveness and promote straighter ball flights. This weighting strategy supports higher launch without enlarging the head profile.Multi-Material Hollow Construction (4–8 Iron)The 4 through 8 irons employ a multi-material hollow construction, combining a Grain Flow Forged 4135+ Chromoly face and neck with a stainless steel back piece. This design increases rebound efficiency and supports higher ball speeds across the face, delivering consistent distance while retaining a forged feel.Partial Hollow 1025E Forging (9–GW)From 9-iron through to gap wedge, the M-15 transitions into a partial hollow Grain Flow Forged 1025E HD body paired with a stainless steel back. This construction prioritises precision, trajectory control, and manoeuvrability in the scoring clubs, giving players greater confidence on approach shots and around the greens.Contoured Ellipse Face with CORTECH (4–8 Iron)The long and mid irons feature Mizuno’s Contoured Ellipse Face, the latest evolution of CORTECH technology. This multi-thickness forged face works in harmony with the hollow construction to optimise ball speed and consistency across the hitting area, while preserving the soft, responsive impact feel expected from Mizuno Pro irons.Refined Sole GeometryRefined sole shaping with added bounce promotes cleaner turf entry and smoother exit. This supports consistent contact and reliable performance from a wide range of lies and swing conditions, particularly through the mid and long irons.Harmonic Impact TechnologyHarmonic Impact Technology, combined with a copper underlay, reduces sound pressure around the 6kHz frequency band. The result is a soft yet solid impact sensation, delivering the controlled feel and feedback that define the Mizuno Pro experience.Nickel Chrome Satin FinishA premium Nickel Chrome Satin finish reduces glare at address while reinforcing the contemporary, tour-informed shaping of the Mizuno Pro M-15.On-Course PerformanceOn the course, the M-15 delivers strong, controlled ball speed through the long and mid irons, with higher launch and improved forgiveness compared to traditional one-piece forged designs. The scoring irons provide precise distance control and a stable, responsive feel, allowing players to flight shots accurately and manage trajectories with confidence.Who It SuitsThe Mizuno Pro M-15 Irons are ideal for accomplished golfers who want modern speed and forgiveness in a compact, tour-inspired shape. They suit players who value forged feel and consistency, but benefit from added launch and stability through the longer irons without sacrificing control in the scoring clubs.Specifications Club Loft Lie Length (60 °) Bounce Dexterity 4 20 ° 60.5 ° 38.75” 2 ° RH 5 23 ° 61.0 ° 38.25” 3 ° RH 6 26 ° 61.5 ° 37.75” 4 ° RH 7 29 ° 62.0 ° 37.25” 5 ° RH 8 33 ° 62.5 ° 36.75” 6 ° RH 9 38 ° 63.0 ° 36.25” 7 ° RH PW 43 ° 63.5 ° 35.75” 8 ° RH GW 48 ° 64.0 ° 35.5” 9 ° RH Built In-House at Nine by NineEvery Mizuno Pro M-15 iron set is assembled in-house at the Nine by Nine Golf workshop.
