Men's Callaway XR Iron Set 4-PW Left HandStyle: 642331-4950443392376-F5
The XR Irons are the first high speed, cavity back, cup-face iron. The improved Cup 360 acts like a spring all across the face for distance that's up to 2 clubs longer.
Revolutionary Ball Speed From Cup 360
Improved face cup technology acts like a spring on shots all across the face to increase ball speeds at every impact location.
Lower CG, More MOI and Ball Speed
The Internal Standing Wave is the ultimate team player. It’s refined the way that we lower CG, increased MOI and gives the face cup the freedom to flex for more ball speed.
Construction And Shape
An iron built for speed needs a different level of refinement and attention, in this case a 2-piece construction that includes a dual heat treatment. It’s precise, meticulous craftsmanship that XR deserves.
