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.

Technology & features

• Channel Back Design: Subtly repositions mass behind the face for a more stable vertical center of gravity, consistent launch conditions and a firmer, tour-preferred sensation.
• Tour-tested and confirmed sole: Flatter camber, sharper leading edge and increased bounce angle for smoother turf interaction – especially for steeper swings.
• Harmonic Impact Technology (HIT): Works with the channel back to fine-tune vibration frequencies for a slightly firmer but solid impact sensation.
• Grain Flow Forged HD: Forged from a single billet of 1025E Pure Select Mild Carbon Steel in Hiroshima, Japan – tighter grain structure for soft feel and consistency.
• Copper Underlay: A thin copper layer beneath the chrome plating softens vibration while keeping a crisp response.
• Soft White Satin finish: Nickel Chrome satin finish for a premium look with reduced glare at address.
