Progressive Sole Design
The sole width on the 3DX RC irons are wider in the longer irons and narrow with the short irons to provide the smoothest transition possible from the hybrids to the short irons and provide the optimum balance of forgiveness and playability throughout the set.
Two tungsten-polymer inserts help spread the weight to the extreme heel and toe to increase stability at impact for more forgiveness on hits all over the face.
Hollow body construction
The hollow body design filled with a carbon fiber cap produces extreme perimeter weighting for maximum forgiveness with little vibration at impact for longer distance with a soft feel.
