About this item The low profile head has a shallow face height and a wide sole with a large step down to keep CG low for easier launch. Increased sole curvature assists with turf interaction. The multi-material Cap Back Design utilizes high-strength stainless steel and ultralight weight polymers. Designed to maximize distance, forgiveness and feel with an extremely low CG. Postioned inside the iron head, the ECHO Damping System uses a soft polymer blend and multiple contact points across the face to channel away harsh vibrations creating a forged-like feel. Patented TaylorMade technology engineered to maximize face flexibility for increased ball speed and forgiveness for mis-hits low on the face.
