The forged, variable-thickness maraging-steel face is thinner for more flexing and creates metal-wood-like bending, resulting in faster ball speeds and a higher max height.

Patent-pending technology relies on an air pocket strategically placed behind the face inside the cavity that attenuates frequencies for improved sound and feel without restricting bending.

Weight savings allow for tungsten weighting inside the club along the sole of the 4-7 irons. This lowers the CG, leading to increased ball speed and higher launch for better stopping power.
