Callaway Quantum Max OS Iron Set 5-PW+AW (2026) NEW

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

Features:

• The Modern 360 degree 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.
• 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.
• 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.
