MIZUNO PRO S-1 IRONS
LEGACY REBORN
Pure Precision. Unmistakable Feel.
The Mizuno Pro S-1 represents the ultimate expression of precision, craftsmanship, and shot-making control. Designed for skilled players who demand exceptional feedback and workability, this pure muscle-back iron combines traditional blade shaping with modern forging innovations.
Grain Flow Forged HD from a single billet of 1025E Pure Select Mild Carbon Steel in Hiroshima, Japan, the S-1 delivers Mizuno's renowned soft and responsive impact sensation. Its innovative Channel Back Design, refined sole geometry, and copper underlay work together to provide consistent performance and exceptional feel.
Engineered for the Purist
Traditional craftsmanship meets modern precision.
Channel Back Design
An innovative channel back geometry strategically redistributes mass behind the face to create a more consistent center of gravity and greater vertical stability. This design supports predictable launch conditions and a solid, responsive feel at impact.
Grain Flow Forged HD
Crafted from a single billet of 1025E Pure Select Mild Carbon Steel in Hiroshima, Japan. Mizuno's high-density forging process refines the grain structure in the impact area, delivering remarkable softness, consistency, and feedback.
Tour-Tested Sole
A refined sole profile featuring reduced camber height, a sharper leading edge, and increased bounce promotes efficient turf interaction. Developed through tour testing, the design helps minimize digging and support clean ball striking.
The Art of Forged Feel
A thin copper underlay beneath the chrome plating helps refine vibration and soften the sensation at impact, while preserving the precise feedback desired by accomplished players.
Combined with Mizuno's Harmonic Impact Technology (HIT), the S-1 delivers a finely tuned sound and tactile response, providing a strong connection between the player and every shot.
Classic Blade. Modern Refinement.
The Mizuno Pro S-1 features a compact muscle-back profile designed for players who value precision, trajectory control, and shot-shaping versatility.
Its Nickel Chrome Soft White Satin finish creates a sophisticated, tour-inspired appearance while reducing glare at address.
