Callaway Quantum Max OS Combo Iron Set (2026) NEW

The Quantum Max OS Hybrid/Iron Combo Set blends maximum forgiveness and speed in friendly, confidence-inspiring set progression. Now you can choose the perfect combination setup for your game.

Features:

• The irons' 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.
• Positions weight low and forward for faster ball speeds and consistent launch. The new Speed Wave 2.0 design frees up even more face flex, boosting energy transfer � especially on low-face strikes.
• The hybrids' new Step Sole Design reduces turf contact on the sole for efficient strikes and consistent center-face contact. A reshaped heel adds stability through impact, helping keep the face square for greater control and accuracy.
• The irons' 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.
