Features and Technology

Modern 360° Undercut Cavity

The Modern 360° Undercut Cavity features an advanced two-piece construction with extreme perimeter weighting and a fully exposed undercut to increase face flex. This design promotes faster ball speeds, higher launch, and enhanced forgiveness across the face.

Progressive Tri-Sole Design

The Progressive Tri-Sole Design adapts sole geometry throughout the set to promote cleaner contact and smoother turf interaction. From long irons to wedges, it helps retain speed and consistency—even on heavy strikes.

Next-Generation AI-Optimized Face Design

The AI-Optimized Face intelligently shapes face thickness based on real-world impact patterns to expand the sweet spot while delivering faster ball speeds and more consistent launch, spin, and dispersion.

Urethane Microspheres

Urethane Microspheres absorb unwanted vibration at impact to improve sound and feel, delivering a softer, forged-like sensation in a high-speed game-improvement iron.

Oversized, Confidence-Inspiring Shape

An oversized head profile promotes higher launch and maximum forgiveness while delivering a confidence-inspiring look at address for more consistent ball striking.
