Mizuno Pro S-1 Iron Set

Who’s It For?

The Mizuno Pro S-1 irons are designed for highly skilled players who prioritize precision, workability, and an exceptionally soft, responsive feel. They are built for golfers who demand full control over their ball flight and shot shaping, with feedback-rich, tour-caliber performance. The combination of the Grain Flow Forged HD process, a copper underlay, and the Channel Back design makes these irons ideal for low-handicap players who can take full advantage of their classic muscle-back profile and sophisticated feel-enhancing technologies.

The Tech Story

The Mizuno Pro S-1 irons are a masterclass in forging technology, designed to provide a feel and performance that is both classic and highly refined. At their core is the Grain Flow Forged HD process, which forges each head from a single billet of 1025E Pure Select Mild Carbon Steel in Hiroshima, Japan, to create a denser grain structure for Mizuno's legendary buttery-soft feel and unmatched consistency. This feel is further optimized by a Copper Underlay, a thin layer of copper beneath the chrome that subtly dampens vibrations to create a purer, more responsive impact sensation. The innovative Channel Back Design redistributes mass for a more stable vertical center of gravity, which ensures consistent launch while providing a solid, tour-preferred feel. This works in harmony with Harmonic Impact Technology (H.I.T.) to meticulously fine-tune vibration frequencies for the ultimate sensory feedback. The irons also feature a Tour-Tested and Confirmed Sole Geometry with a flatter camber, sharpened leading edge, and increased bounce, all designed to facilitate smoother turf interaction and prevent digging. Finally, a Soft White Satin Finish not only gives the irons a premium, tour-inspired look but also reduces glare to help with focus at address.
