Callaway Apex Muscleback Irons are true muscle backs inspired by the Tour and suited for the best of the best players.
Tour Shaping and Design
The world’s best players provided extensive feedback to help make this a true muscleback iron. This is a classic shape and style, with a traditional, slightly thinner topline, and a beautiful bright chrome finish in our smallest blade head shape. And we’ve advanced our CG positioning to optimize the CG for outstanding control.
High Performance 20V Grooves
Precision grooves are built in to promote the high level of control and consistent spin that muscleback players expect out of any playing conditions. The 20V grooves also stand out for reducing fliers from the rough to deliver even more control.
Forged From 1025 Carbon Steel
This players iron was engineered for a remarkably soft feel that Tour players want, with the exact craftsmanship and precision they expect – only achieved through our premium forging process.
