While designing the XCG-4 irons our engineers were asked to design a club that would deliver the stunning performance that sets Exotics apart from the others. The result is an iron that boasts our thinnest face. Measuring less than 2.2mm the face has different levels of thickness to promote distance and enhanced feel. That combined with the dual tungsten weights behind the face produce our highest rebound rate and moment of inertia (MOI - the club’s ability to resist twisting) in an Exotics iron.
A deep, undercut cavity moves weight to the outer edges of the clubhead for enhanced forgiveness and a higher MOI. The deep undercut cavity, the wide sole design, the perimeter weighting and the tungsten sole weights help to lower the center of gravity, optimize the trajectory and enhance the MOI. The result is exceptional forgiveness and a six iron with a MOI of 2,750, exceptionally high for any iron.
