Legacy Reborn

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 optimizes this experience, subtly refining vibration patterns to produce the purest, most satisfying feedback.

Channel Back Design

The innovative Channel Back Design subtly repositions mass behind the face to achieve a more stable vertical center of gravity, resulting in consistent launch conditions. Simultaneously, it offers a firmer, tour-preferred sensation, enhancing responsiveness without sacrificing the purity of feel.

Tour-Tested And Confirmed

The S-1 sole has been carefully refined through tour input, featuring a flatter camber profile, sharpened leading edge, and increased bounce angle. This design ensures smoother turf interaction—particularly beneficial for shallower swings—minimizing digging and allowing players to maintain aggressive angles of attack with confidence.

Soft White Satin Finish

The irons are finished in a sophisticated Nickel Chrome Soft White Satin, offering a premium, tour-inspired aesthetic. Beyond its visual appeal, the satin treatment effectively reduces glare at address, promoting unwavering focus and visual clarity in all lighting conditions.

Nothing Feels Like A Mizuno

  • Harmonic Impact Technology (HIT): Proprietary Harmonic Impact Technology works in tandem with the channel back geometry to fine-tune vibration frequencies, delivering a slightly firmer—but still satisfyingly solid—impact sensation.
  • Further Optimized Grain Flow Forged HD (High Density): From a single billet of 1025E mild carbon steel in Hiroshima Japan for unmistakable Mizuno feel through impact.
  • Copper Underlay: Incremental softer impact feel combined with HIT, for the ultimate impact sensation.

Nippon N.S Pro Modus 3 120 Steel: Unique development concept designed for control. The N.S. PRO Modus 3 series shafts are popular with touring pros because they offer optimal performance in three key areas. The desired trajectory as a result of the unique structure of a stiff tip section and softer midsection. Accurate distances due to the unique raw steel material and accompanying heat treatment. And tight dispersion coming from the exacting tolerances of the highest quality level. The high-rigidity design of the tip steadies impact to help minimize unwanted spin while creating a stronger trajectory. The low rigidity in the midsection improves shaft control so the player with any tempo can more easily control their shots, while the low but rigidity improves swing tempo and contributes to a comfortable, smoother feeling upon impact.
True Temper AMT Tour Silver: AMT Tour Silver is the middle-heavy weight option in the AMT range and delivers a mid trajectory and spin.
