Callaway X-20 Iron Set

A 360-Degree Undercut Channel maximizes perimeter weighting by moving the Center of Gravity (CG) lower and deep in the clubhead, enlarging the hitting area and stabilizing the clubhead for more forgiveness
• Extreme Notch Weighting technology enhances perimeter-weighting for higher Moment of Inertia (MOI) for greater forgiveness and more stability at impact
• Constructed of soft, durable 17-4 stainless steel with Tru-Bore technology for soft feel and shot-making control
• The Progressive Wall Reduction System lowers the Center of Gravity 6% more than in the X-18
• S2H2 technology further enhances perimeter-weighting for improved forgiveness, particularly on off-center hits
