Mizuno, renowned for its relentless pursuit of forging perfection, have unveiled the Mizuno Pro S-1 irons—an exciting new addition to its celebrated Signature Series.
Crafted for the discerning player, the S-1 is a bold step forward in Mizuno’s mission to deliver precision engineering, peerless feel, and continuously refined performance.
TRADITION
The Mizuno Signature Series reflects the company’s long-standing commitment to producing meticulously designed clubs that balance tradition with the needs of the modern golfer.
The Mizuno Pro S-1 follows the introduction of the hugely popular Mizuno Pro S-3 irons in January, offering players another standout option within the family.
The Mizuno Pro S-1 irons are pure muscle backs, designed for players who demand ultimate precision and workability.
At the core of the Mizuno Pro S-1 is Mizuno’s Grain Flow Forged HD process, carefully executed in Hiroshima, Japan.
Forged from a single billet of 1025E Pure Select Mild Carbon Steel, the S-1 delivers the unmistakably soft and responsive feel through impact that Mizuno is globally known for.
The inclusion of a copper underlay further optimises this experience, subtly refining vibration patterns to produce the purest, most satisfying feedback.
MAKING A DIFFERENCE
Developed and tested with input from tour professionals, the S-1 incorporates a Channel Back Design that redistributes mass for greater vertical stability and a more consistent centre of gravity.
This design works seamlessly with Mizuno’s Harmonic Impact Technology, which fine-tunes the feel by adjusting the club’s vibration frequencies to deliver even more responsive feedback.
Building on Mizuno’s continuous drive for improvement, the S-1 introduces a re-engineered sole that has been precisely shaped to optimise turf interaction.
WHAT’S NEW
Compared to its predecessor, the Mizuno Pro 241, the S-1 sole features a flatter camber, a sharper leading edge, and an additional degree of bounce.
The result is a club that offers greater forgiveness for shallower attack angles while reducing the chance of digging—giving players the confidence to commit to every shot.
Visually, the S-1 has been crafted to appeal to the modern, competitive golfer. It features a compact, tour-preferred profile with a square toe design, a thin topline, and straight edges that convey discipline and purpose.
The Soft White Satin finish not only complements its sophisticated appearance but also serves to reduce glare at address.
