With an advanced two-piece perimeter weighting design, fully exposed undercut cavity back and refined confidence-inspiring shapes, Callaway’s new Quantum irons promise the opportunity to hit more greens.
The Quantum irons deploy a Modern 360° Undercut cavity designed to deliver faster ball speeds, higher launch and more forgiveness across the face. This is thanks to its two-piece design with extreme perimeter weighting and a full undercut cavity for added flex where golfers need it most.
The irons also have the progressive Tri-Sole design that promotes cleaner, more consistent contact across the set. The re-engineered sole geometry adapts from long irons to wedges for smooth turf interaction and efficient speed retention, even on heavy strikes.
The next generation AI-optimized face delivers faster ball speeds and more consistent launch, spin and dispersion by intelligently shaping the face to match real-world impact patterns and expand the sweet spot. Urethane microspheres enhance sound and feel at impact by absorbing unwanted vibration, delivering a softer, forged-like sensation in a high-speed game-improvement head.
Quantum Max inspires confidence with powerful speed, consistent carry and forgiving performance across the face in a clean, modern shape. Quantum Max OS has an oversized shape designed to help golfers hit it more solid across the face with higher launch and maximum forgiveness. Both retail for $157 per stick or $1099.99 per 7-piece set ($171/$1199.99 in graphite).
Quantum Max Fast ($178/$1249.99) pairs an ultra-lightweight design with an oversized, confidence-inspiring shape to be an easy-to-launch iron that helps moderate swing speed players get more height, speed, distance and stopping power.
