The Quantum Irons are engineered to deliver exceptional speed, high launch, consistent carry and forgiving performance across the face. The irons are underpinned by Callaway’s Modern 360 Undercut cavity that’s designed to deliver these fast ball speeds and high launch in a refined game-improvement shaping. This advanced two-piece design provides perimeter weighting and a fully exposed undercut for added flex where golfers need it most.

The Progressive Tri-Sole Design in Quantum Irons promotes cleaner, more consistent contact across the set, with a re-engineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention — even on heavy strikes. This lineup is available in Max, Max OS (super game-improvement) and Max Fast offerings.
