Key Tech

Quantum Max OS blends confidence with maximum forgiveness, powerful speed, and consistent carry — all in an oversized shape designed to help golfers hit it more solid across the face.
Quantum Max Fast is a lightweight, easy-to-launch iron that helps you get more height, speed, and distance. This model is designed to be fast and forgiving, while also promoting a high launch for moderate swing speed golfers.
Modern 360 ° Undercut
The Modern 360° Undercut Cavity is designed to deliver faster ball speeds, higher launch, and more forgiveness across the face, thanks to its advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex where golfers need it most.
Progressive Tri-Sole Design
The Progressive Tri-Sole Design promotes cleaner, more consistent contact across the set, with a reengineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention — even on heavy strikes.
Next Generation Ai-Optimized Face Design
The Next Generation AI-Optimized Face delivers faster ball speeds and more consistent launch, spin, and dispersion by intelligently shaping the face to match real-world impact patterns and expand the sweet spot.
Urethane Microspheres
Urethane Microspheres enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.
