The Callaway Quantum Max OS Iron range is designed to deliver maximum forgiveness, powerful ball speed, and consistent carry distances in a confidence-inspiring oversized profile. Built to help golfers strike the ball more solidly across the face, these game-improvement irons promote higher launch and reliable performance from tee to green.
The Modern 360 degrees Undercut Cavity is engineered to produce faster ball speeds, higher launch, and increased forgiveness across the face. Its advanced two-piece construction features extreme perimeter weighting and a fully exposed undercut, allowing the face to flex more efficiently where golfers need it most.
The Progressive Tri-Sole Design promotes cleaner turf interaction and more consistent contact throughout the set. With re-engineered sole geometry that transitions from long irons to wedges, it helps maintain speed and launch while improving performance on heavy or imperfect strikes.
The Next-Generation Ai-Optimised Face is intelligently shaped using real-world impact data to deliver faster ball speeds and more consistent launch, spin, and dispersion. By expanding the effective hitting area, it helps golfers achieve straighter, more predictable iron shots.
Urethane Microspheres are integrated into the clubhead to absorb unwanted vibration at impact, enhancing sound and feel. This technology delivers a softer, forged-like sensation while retaining the speed and forgiveness expected from a high-performance game-improvement iron.
Designed for higher launch and maximum forgiveness, the Quantum Max OS irons feature an oversized shape that inspires confidence at address. Ideal for golfers seeking easy distance, improved consistency, and greater forgiveness, they offer dependable performance across the entire face.
