Product Details

Callaway's new Apex 21 MB Irons are a supreme work of craftsmanship, delivering irresistibly soft feel, premium looks and tour sculpted shaping in a set targeting the finest ball strikers.

Focusing on true precision, Apex 21 MB is a pure muscleback in every way. Its classic shape features a thin topline, refined sole, compact blade length and stunning chrome finish to suit the eye of tour players through to single-digit handicappers.

New to an Apex MB is the high-precision 20V grooves. This innovative addition provides unparalleled control with ultra-consistent spin in all conditions from calm humid climates through to the fury of traditional British links courses. A standout attribute is the 20V grooves' ability to drastically reduce fliers so golfers can trust their yardage and commit to the shot with confidence. 

To fine-tune CG, Apex 21 MB features a screw-in weight in the back of each head. These weights are specific to loft, length, weight of shaft and many other factors to allow Callaway to precisely determine swing weights as well as CG location for added control.
