Callaway Quantum Max Fast Irons

Quantum Max Fast is a lightweight, easy-to-launch iron that helps you get more height, speed, and distance. This model is designed to be fast and forgiving, while also promoting a high launch for moderate swing speed golfers.

Modern 360° Undercut

The Modern 360° Undercut Cavity is designed to deliver faster ball speeds, higher launch, and more forgiveness across the face, thanks to its advanced two-piece design with extreme perimeter weighting and a fully exposed undercut for added flex where golfers need it most.

Progressive Tri-Sole Design

The Progressive Tri-Sole Design promotes cleaner, more consistent contact across the set, with a reengineered sole geometry that adapts from long irons to wedges for smooth turf interaction and efficient speed retention — even on heavy strikes.

Next Generation Ai-Optimized Face Design

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

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.

Oversized, Confidence-Inspiring Shape

Quantum Max Fast pairs an ultra-lightweight design with an oversized, confidence-inspiring shape, helping moderate swing speed players launch higher and carry farther with reliable stopping power.
