Unlike most hollow-bodied irons, the Ai150 employs a forged body and face, resulting in an exceptional feel at impact. A forged 455 Face Cup in the three through seven irons yields tremendous power, while a 17-4 face in scoring clubs, they offer greater control, precision, and accuracy.

The Ai150 features an Ai10x Face, Callaway's most advanced face design to date. Utilizing real player data and cutting-edge machine learning, Ai10x delivers ten times more control points than Ai Smart Face. With thousands more smart points, Ai150 produces a vastly tighter dispersion and exceptionally consistent launch and spin across the face.

Callaway strategically positions MIM weighting in the Ai150 based on each club's ideal ball flight. Optimizing the center of gravity ensures the perfect launch window throughout the set, with high-launching long irons and more accurate, controlled scoring irons.
