Get the high performing irons you’ve been dreaming of with Callaway Golf’s GBB Pro Steel Iron Set. They used the industry’s leading technologies and paired them with premium materials to make advancements in distance, speed, control, and forgiveness.
Pro Design
This pro set is designed for high-performance players by creating a slightly smaller head shape with a thinner sole and less offset. These features come together to create irons that increase ball speed and forgiveness.
Improved 360 Face Cup Technology
To maximize ball speed on center hits and to reduce distance loss on off-center hits, Callaway created a thinner rim on its 360 Face Cup Technology.
Sturdy Exo-Cage
To provide more speed and distance, the face can now increase its flexibility from a stiffened Exo-Cage structure that supports it. This structure can take on more impact load to allow the face to efficiently transfer energy to the ball to make balls fly faster and farther.
Optimized Irons
Each iron in the set is uniquely optimized to bring out its best performance. A specially created tungsten weight was made for each iron to provide a CG that best suits each iron. The individualized CG allows a long carry for long irons and a high CG for short irons that promotes more control with an easier launch.
