Innovation without boundaries, with the new Callaway GBB Epic Irons (Steel).
Callaway GBB Epic Irons (Steel) Features:
Next-Generation 360 Face Cup Technology for Longer Average Distance
Advancing the industry-leading face technology that made Callaway the #1 Iron in golf. The rim of the Face Cup is 1 mm at its thinnest point to add even more ball speed on center hits and also further minimizing distance loss on off-center hits.
Exo-Cage for Energy Lensing and Maximum COR
Exo-Cage head construction stiffens the body to allow the face to take on more of the load of impact. This is known as “Energy Lensing” – it promotes faster ball speed for longer distance, and it also helped raise the COR in Epic Irons right up to the limit in each iron.
MIM’ed Tungsten Infused Standing Wave To Optimize CG Location
Multi-material construction demands strict tolerances, seamless fit and secure bonding. Incorporating tungsten in the Internal Standing Wave allowed Callaway engineers to precisely position the CG in each individual iron. This includes a lower CG for easier launch and also long carry in the long irons. Whilst higher CG in the short irons for a lower, more controllable flight, and also left-to-right CG control in tandem with the hollow hosel.
