Callaway Golf Apex 21 Steel Irons


Callaway Apex 21 Golf Irons
Forged Performance With A.I. Flash Face Cup

The new Callaway Apex 21 Irons deliver an extraordinary level of forged performance and craftsmanship that we’ve never seen before. They’re the first forged iron designed with Artificial Intelligence for faster ball speeds and improved spin consistency.

A.I.-designed Flash Face Cup is in a forged Apex Iron for the first time ever. The unique A.I. architecture in each iron creates high ball speeds and increased spin robustness across the face. They’re engineered for impressive distance and pinpoint control. For the first time Callaway have implemented Tungsten Energy Core into an Apex Iron. With 5x the tungsten of Apex 19, they have precisely position the Center of Gravity to promote outstanding launch throughout the set, and more forgiveness on off-centre shots.

Apex Irons are renowned for their pure feel, and Apex 21 is no different. The body of the iron is 100% forged from a 1025 mild carbon steel body, and our patented urethane microspheres deliver exceptional sound and feel at impact. The improved shaping also helps to enhance feel through the turf.

Complete with a high performance shaft, these irons feature the True Temper Elevate 95 shaft that provides a mid-light weight performance with towering and powerful ball flight.
