Callaway XR Irons - Graphite
The new Callaway XR Irons with graphite shafts are Callaways longest cavity back irons ever. They have incorporated their patented 360 Face Cup to maximize face flex. This helps make the clubs deliver distance up to 2 clubs longer by allowing the face to thin, which increases face flex on impact. Increasing the face flex increases the ball speeds and thus distance. It also incorporates the Internal Standing Wave which lowers the CG and allows more freedom for the face to flex. Lower CG increases the launch angle to help get the ball airborne for a higher flight. Callaway has also changed the way they construct their irons. They now have a 2-piece construction with a dual heating process that enables them to deliver incredible club and ball speed.
