Built In Technology For Outrageous Speeds
The XR is an iron built for speed. Callaway have taken the Cup 360 that's redefined ball speed in fairway woods and brought it to irons for outstanding results.
The improved face cup technology acts like a spring on shots hit low on the face to increase ball speeds. The speed is higher at every other impact location on the face too for better results across the club face. The XR promotes a lower CG with more MOI thanks to the Internal Standing Wave which 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.
With a new 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.
