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.

Built for higher launch and maximum forgiveness, Quantum Max OS delivers a confidence-inspiring look at address with performance designed to help you produce more consistent results.

Key Technologies

• Modern 360° Undercut – Designed to deliver faster ball speeds, higher launch, and more forgiveness across the face through a two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex.
• Progressive Tri-Sole Design – Promotes cleaner, more consistent contact across the set with 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 – Delivers faster ball speeds and more consistent launch, spin, and dispersion by shaping the face to match real-world impact patterns and expand the sweet spot.
• Urethane Microspheres – Enhance sound and feel at impact by absorbing unwanted vibration for a softer, forged-like sensation in a high-speed game-improvement head.
• Oversized, Confidence-Inspiring Shape – Built for higher launch and maximum forgiveness in an oversized shape that inspires confidence at address.
