About this product

The Quantum MAX OS takes the 360° undercut cavity, AI-optimized face, and Progressive Tri-Sole of the Quantum MAX and makes them even more forgiving.

Right or left hand, with True Temper Elevate steel and Project X Denali graphite options.

Features & specs

• Modern 360° Undercut Cavity: 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: 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 ball speed retention — even on heavy strikes.
• Next Generation Ai-Optimized Face Design: 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: Enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.
• Oversized, Confidence-Inspiring Shape: Built for higher launch and maximum forgiveness — all in an oversized shape that inspires confidence at address.
