Callaway Quantum Max OS Golf Irons - Steel
The Callaway Quantum Max OS Steel Irons are engineered to deliver exceptional forgiveness, strong ball speed, and dependable carry distances in an oversized, confidence-boosting design. Built for golfers who want easier launch and more consistent strikes, these game-improvement irons help maintain performance across the entire face.
The Modern 360-degree Undercut Cavity is designed to maximise face flex for faster ball speeds and higher launch. Its advanced two-piece construction combines extreme perimeter weighting with a fully exposed undercut, enhancing forgiveness and distance on both centred and off-centre strikes.
The Progressive Tri-Sole Design supports cleaner turf interaction and improved consistency throughout the set. With reworked sole geometry that progresses from long irons to wedges, it helps retain speed and launch while reducing the impact of heavy contact.
Developed using real-world impact data, the Next-Generation Ai-Optimised Face promotes faster ball speeds with more consistent launch, spin, and dispersion. By expanding the effective hitting area, it helps golfers produce straighter, more predictable iron shots.
Urethane Microspheres are strategically integrated into the clubhead to absorb unwanted vibration at impact. This improves sound and feel, delivering a softer, forged-like sensation while maintaining the speed and forgiveness expected from a high-MOI iron.
Designed to promote higher launch and maximum forgiveness, the Quantum Max OS irons feature an oversized profile that inspires confidence at address. Ideal for golfers seeking easy distance and improved consistency, they deliver reliable performance across the full set.
