Callaway Quantum Max OS Irons [GRAPHITE][5-PW][RIGHT][REG][DENALI SILVER 60]

Callaway Quantum Max OS Irons

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.

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-Optimised Face Design
The Next Generation Ai-Optimised 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.

Oversized, Confidence-Inspiring Shape
Quantum Max OS is built for higher launch and maximum forgiveness — all in an oversized shape that inspires confidence at address.
