The Callaway X-22 irons feature a 10-percent higher MOI than its predecessors through maximizing perimeter weighting. Its center of gravity has been preserved to generate optimal ball flight and its precision notch weighting positions more weight to the perimeter to create more stability and forgiveness, all while maintaining a tour-inspired head shape with a thinner top line and narrower sole. The result is an iron that is incredibly forgiving, while still incorporating the look and feel that better players prefer.
