Callaway XR Pro Iron Set

Features and benefits of the Callaway XR Pro Irons:

REVOLUTIONARY BALL SPEED FROM CUP 360: Improved face cup technology acts like a spring on shots hit low on the face to increase ball speeds.
LOWER CG, MORE MOI AND BALL SPEED: The Internal Standing Wave has lowered CG, increased MOI and gives the face cup the freedom to flex for more ball speed.
NEW CONSTRUCTION AND SHAPE: A players iron needs a different level of refinement and attention, in this case a 2-piece construction that includes a dual heat treatment with a head shape that is more compact, has a thinner topline and narrower sole width.
