The Quantum MAX OS combine confidence with maximum forgiveness, high speed and consistent trajectories - all in an oversized shape that helps golfers hit the ball more solidly across the clubface.

Advanced 360° Undercut
The advanced 360° Undercut Cavity is designed to deliver higher ball speeds, higher launch and more forgiveness across the face. This is achieved through the advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flexibility where golfers need it most.

Progressive Tri-Sole Design
The progressive tri-sole design promotes cleaner, consistent contact across the entire set, with a revised sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed maintenance - even on fat shots.

Next generation AI-optimized face design
The next generation AI-optimized face delivers higher ball speeds and more consistent launch, spin and dispersion by intelligently adapting the face to actual impact patterns and increasing the sweet spot.

Urethane Microspheres
Urethane Microspheres improve sound and feel at impact by absorbing unwanted vibrations and providing a softer, forged feel in a high-speed Game Improvement head.

Oversized, confidence-inspiring shape
Quantum Max OS irons are designed for higher launch and maximum forgiveness - all in an oversized shape that inspires confidence at address.
