Mizuno Pro S-1 Irons
Pure Muscle Back Precision with Unmatched Feel
The Mizuno Pro S-1 Irons represent the pinnacle of forged craftsmanship — pure muscle backs designed for players who demand ultimate precision, control, and workability. Every detail has been meticulously engineered to deliver the soft, responsive feel that defines Mizuno’s heritage of performance excellence.
At their core lies the renowned Grain Flow Forged HD process, expertly executed in Hiroshima, Japan, using a single billet of 1025E Pure Select Mild Carbon Steel. This forging method creates the legendary Mizuno feel — buttery smooth through impact, with unmatched feedback and control. A copper underlay subtly refines vibration patterns, enhancing the soft, solid sensation for which Mizuno irons are revered.
