The Callaway XR Iron is an iron built for speed. Callaway took the Cup 360 that redefined ball speed in fairway woods and brought it to irons. The improved Cup 360 acts like a spring on shots hit low on the face and increases ball speeds everywhere else on the face, too. The distance is incredible, and that's just the start. When you factor in the lower center of gravity (CG), all that forgiveness, and the face flex of the Internal Standing Wave, along with the precise two-piece, dual-heat construction, you can see why Callaway wanted to get these irons in golfers' hands right now. They're looking forward to redefining the iron category, again.

*** PRODUCT FEATURES: ***

* Revolutionary Ball Speed from Cup 360: The improved face cup technology even acts like a spring on shots hit low on the face in order to increase ball speeds. The speed is higher at every other impact location on the face, too

* Lower CG, More MOI, and More Ball Speed: The Internal Standing Wave is the ultimate team player. It's refined the ability to lower the CG and to increase the moment of inertia (MOI), and it gives the face cup the freedom to flex for more ball speed.

* New Construction and Shape: An iron built for speed needs a different level of refinement and attention. In this case, its two-piece construction includes dual-heat treatment. It's precise, meticulous craftsmanship that XR deserves.
