Undercut Cavity, engineered to deliver faster ball speeds and higher launch across the face. The advanced two-piece construction features extreme perimeter weighting and a fully exposed undercut, allowing the face to flex more efficiently where golfers need it most. This design increases forgiveness on off-centre strikes while maintaining consistent carry distances.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eNext Generation Ai-Optimised Face Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe Next Generation Ai-Optimised Face intelligently shapes face geometry based on real-world impact patterns. By expanding the effective sweet spot, it delivers faster ball speeds with more consistent launch, spin, and dispersion, helping shots fly more predictably even when contact isn’t perfect.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eProgressive Tri-Sole Design\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eThe Progressive Tri-Sole Design adapts sole geometry throughout the set, promoting cleaner turf interaction from long irons through wedges. Wider soles in the long irons help launch the ball higher and retain speed, while more refined soles in the short irons and wedges improve control and consistency through impact, even on heavier strikes.\u003c\/p\u003e\u003ch3\u003e\u003cstrong\u003eUrethane Microspheres\u003c\/strong\u003e\u003c\/h3\u003e\u003cp\u003eUrethane Microspheres are positioned within the head to absorb unwanted vibration at impact.
