The Callaway X-22 Irons incorporate what they call “Precision Notch Weighting”. Which was designed to give you increased stability and forgiveness, but still keep the center of gravity at the optimal position. By keeping the weight positioned closer to the perimeter which increases the moment-of-inertia the clubs give you that needed stability. The perimeter weighting of the X-22s has been maximized for a moment of inertia (MOI) which helps gives that forgiveness off of center strikes. The Callaway X-22 Iron incorporates the latest technologies with a sleek design. It’s designed around the Tour-Inspired Head shape and also retains the large square look. It also incorporates their VFT Technology to give you more ball speed when you make a shot. It has a large sweetspot and 360-Degree undercut channels. These are some of the Callaway’s X-22 irons best features.
