COR2 is a low density, high speed, vibration dampening material with explosive C.O.R. (coefficient of restitution) properties. Injected into PXG’s forged, hollow-body irons, the material supports an extremely efficient energy transfer, helping produce a more consistent response, incredible accuracy and an outstanding feel at impact.

The face is formed from ultra-thin HT1770 high-strength maraging steel that measures just 1.5mm thick, about the thickness of a penny. The weight saved by using a thin face allows more mass to be positioned in areas of the club head that help to optimize launch conditions and MOI.

Without changing the optical size of the face, PXG’s internal face perimeter cut-out design creates a 15% larger functional face area. This yields a larger trampoline for the COR2 material to react, producing faster ball speeds and significantly improving mishit performance.

An angled back surface tapers the thickness of the club from heel-to-toe, while visually the top rail remains constant and parallel to the face. This geometry allows more mass to be positioned to the toe side of the club head for an increased MOI.
