X-Series Irons from Callaway Golf have long been favored by some of the best players in the world because of their performance-enhancing technologies and by recreational golfers due to their forgiveness and great looks. The new X-18 Irons combine many of the same patented Callaway Golf core technologies used in earlier X-Series models with a new traditional head shape and size, and high-polish finish. The X-Series legacy of performance continues.

• ----------Deeper 360-Degree Undercut Channel maximizes perimeter weighting, allowing more weight to be moved to the heel and toe, thereby improving forgiveness
• ----------Extreme Notch Weighting raises the MOI (moment of inertia) for increased stability and reduced distance loss on off-center hits
