Callaway XR OS Golf Iron Sets Frequently Asked Questions
Product Description
Callaway XR OS Irons feature Enhanced Cup 360 Face Cup Technology to maximize ball speeds through added flex at impact. The Internal Standing Wave moves the center of gravity (CG) lower and forward to increase the moment of inertia (MOI) for increased forgiveness. With a lower CG and higher MOI, the face cup is able to flex more at impact to generate greater ball speeds for higher distances. XR OS irons are constructed of 17-4 stainless steel for superior performance and durability and come standard with the True Temper Speed Step 80 Steel Shaft and Callaway Universal Grip. Callaway XR OS irons are an excellent option for all levels of golfers seeking easier launch, greater forgiveness and added distance.
