The Callaway X-18 and X-18 Pro Series Irons are the latest version of the best-selling X-Series Irons that have long been the favorite of a broad spectrum of the world's golfers. With each iron containing years of knowledge built into a new, sleek package, both X-18 models incorporate the player-trusted and Tour-tested performance features that have made Callaway Golf the worldwide leader in iron technology.

The successor to the popular X-16 and X-16 Pro Series Irons begin with the patented core technologies that have made the Callaway Golf brand the market leader. Extreme Notch Weighting, a proprietary visible feature that raises each iron's Moment of Inertia (MOI) for increased stability and better results on off-center hits, combines with a deeper 360-degree Undercut Channel to achieve new heights of forgiveness.

The Callaway X-18 irons are the next line in a legacy of stainless steel precision tools for your precision shots. 2H2 (Short Straight Hollow Hosel), a staple of Callaway Golf irons for more than 15 years, allows weight to be moved lower and to the more useful perimeter area of the clubhead. An integral element of the S2H2 design is Tru-Bore Technology, which extends the shaft tip completely through the clubhead to the sole for greater feel and superior control. Finally, VFT (Variable Face Thickness) face design technology allows Callaway Golf to raise or lower the center of gravity for optimum trajectory with each iron in the set: resulting in a higher launch angle in the long irons and better trajectory height control in the short irons and wedges.

The Callaway X-18 Irons also feature a standard progressive offset throughout the set and fully balanced sole engineered to improve turf interaction and workability. The reduced offset and slightly thinner sole also increase confidence at address.

The ideal balance of performance and forgiveness in irons built for every type of shot, with a deeper 360-degree undercut channel for forgiveness, more extreme Notch Weighing for stability.
