We Built a Cage and Unlocked More Distance

Big Bertha OS Irons incorporate a revolutionary clubhead construction, called the Exo-Cage, that promotes more distance in an entirely new way. How? The Exo-Cage’s extraordinary combination of strength and light weight allows Callaway engineers to distribute more discretionary weight into strategic locations to promote more forgiveness and to allow our next-generation 360 Face Cup technology to function more efficiently. The result is more ball speed across the face to give you more distance on every swing.
