Callaway Big Bertha OS Iron Set

More Forgiveness and Ball Speed from New Exo-Cage Technology: Allows more weight to be positioned in strategic locations to increase forgiveness.
Even More Ball Speed from Next Gen 360 Face Cup: Elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance.
Higher Launch for Longer Carry from Tungsten-Loaded Standing Wave: Lowers the CG to promote a higher launch angle.
Progressive Center of Gravity for Increased Control: Moving the CG location progressively lower promotes higher launch and long carry in the long-irons and increased control in the short-irons.
