The Callaway® Big Bertha OS Iron Set for Men promotes more distance in an entirely new way, led by an extraordinary light and strong Exo-Cage that strategically positions weight to increase forgiveness. This new design allows the golf irons in this Callaway set to produce even faster ball speeds and more distance through the new 360 Face Cup design. This next-generation Face Cup technology elevates clubface COR closer to the USGA limit to produce even stronger results. Tungsten-Loaded Standing Wave technology in the sole lowers the CG to promote a higher launch angle for longer carry and more ball speed on shots struck low on the face.

Callaway OS Irons also boast Progressive Center of Gravity technology, which entails moving the CG location progressively lower in each head from the highest-lofted to the lowest-lofted. This promotes higher launch and long carry in the long irons and increased control in the short irons. The Big Bertha OS Iron Set for Men puts Callaway's newest technology in your hands for game-changing performance. Some sets shown here substitute Big Bertha OS Hybrids for the long irons to help you hit longer shots with greater consistency and authority. These Callaway irons and hybrids are outfitted with Project X graphite or steel shafts in your choice of flex.
