The XCG-4 irons create playability across the entire set, allowing any player to play these clubs. When engineers at Tour Edge were asked to create a club that set them apart they designed the thinnest face (2.2mm to be exact) on any Tour Edge iron up to this point. Beyond this innovation, the club has dual tungesten weights behind the face to produce a high rebound rate and MOI. The deep undercut cavity moves weight to the outer edges enhancing forgiveness. This is the perfect iron for any player! Pick yours up from 2nd Swing now.
