Custom Callaway Quantum Max OS Irons

Oversized Easy Distance

Callaway Quantum Max OS blends confidence with maximum forgiveness, powerful speed, and consistent carry in an oversized shape designed to help golfers hit it more solid across the face and launch it higher with ease.

Modern 360° Undercut

A two-piece cavity construction with extreme perimeter weighting and a fully exposed undercut increases face flex to deliver faster ball speeds, higher launch, and more forgiveness across the face.

Progressive Tri-Sole Design

Progressive Tri-Sole geometry improves turf interaction and consistency from long irons to wedges, helping maintain speed and launch even on heavier strikes.

Next Generation Ai-Optimized Face Design

Ai shaping expands the sweet spot and improves consistency by tuning launch, spin, and dispersion around real-world impact patterns.

Urethane Microspheres

Urethane Microspheres absorb unwanted vibration for improved sound and a softer feel at impact.

Oversized, Confidence-Inspiring Shape

An oversized profile inspires confidence at address and promotes higher launch with maximum forgiveness across the face.
