Callaway Quantum Irons

The Quantum Irons are engineered for exceptional speed, high launch, consistent carry, and forgiveness across the entire face. Built with Callaway’s Modern 360 Undercut cavity, they generate fast ball speeds and easy launch in a refined game-improvement shape. The advanced two-piece design adds perimeter weighting and a fully exposed undercut for added flex where it’s needed most. A Progressive Tri-Sole design enhances turf interaction and maintains speed, even on heavy strikes. Available in Max, Max OS, and Max Fast models.
