HOLLOW-BODY PERIMETER WEIGHTING Hollow-body perimeter weighting produces distance properties of a metalwood in an iron-like design. Hollow-body perimeter weighting produces maximum ball speed off an iron. The hollow-body design makes for an extremely low and back CG, helping to create a very forgiving and powerful face. SLICE-FIGHTING OFFSET DESIGN The offset design acts as built-in slice fighting technology. This helps square the clubhead at impact to produce anti-slice ball fights.
