Next generation 360 degree face technology in the Callaway Steelhead XR Graphite Irons increases ball speeds more efficiently on both center and off-center hits. Steel-infused urethane bar behind the face improves feel and lowers the center-of-gravity for higher launch. The Hollow Bore-Thru hosel saves weight and repositions weight for more forgiveness. Progressive center-of-gravity throughout the irons improves launch and distance in the long irons and control and playability in the short irons.
