A thinner, stronger face and sole structure re-engineered for speed. Using a high strength 17-4 stainless steel L-Cup face design. We've produced a larger Sweet Zone delivering distance, more forgiveness and ultra precise irons.CNC Milled Grooves improve groove structure. This increases spin and optimizes trajectory throughout the set. The result is improved control and workability giving you added confidence when you're attacking the pin.Weight is strategically removed from the center of the club head and redistributed around the face lower and further back. Lower and centered CG placement creates more precision without sacrificing forgiveness.
