Callaway Men's Big Bertha OS 6PC Iron Set - Steel
The new 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. In short, Callaway Built a Cage and Unlocked More Distance.
Features:More Forgiveness and Ball Speed from New EXO-CAGE Technology -
The uniquely light-and-strong design of the EXO-CAGE allows more weight to be positioned in strategic locations to increase forgiveness while also helping our next-generation 360 Face Cup technology to function more efficiently.
Even More Ball Speed from Next Gen 360 Face Cup -
Next-generation 360 Face Cup technology 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 -
Tungsten-Loaded Standing Wave technology in the sole lowers the center of gravity to promote a higher launch angle for longer carry and more ball speed on hits low on the face. Progressive Center of Gravity for Increased Control -
Progressive Center of Gravity technology entails moving the CG location progressively lower in each head from the highest-lofted to the lowest-lofted, promoting higher launch and long carry in the long-irons and increased control in the short-irons. Steel shaft -
