The Callaway Apex 21 Irons are the first forged irons designed with Artificial Intelligence for faster ball speeds and improved spin consistency. They feature a massive Tungsten Energy Core for increased forgiveness and enhanced shaping for better turf interaction. Get superior performance and iconic feel on every swing with the Apex 21 Irons.
Higher ball speeds and increased spin robustness across the face is created from the unique A.I. architecture in each iron.
Callaway's Tungsten Energy Core is featured in the Apex 21 irons for the first time ever. This means 5x more tungsten than the Apex 19 irons which helps to position the Center of Gravity to promote better launch and more forgiveness on off-center shots.
The body of the Apex 21 Irons are forged from 1025 mild carbon steel and also include Callaway's patented urethane microspheres for exceptional sound and feel. The head shape is improved from previous generations to further enhance the feel through the turf.
