Big Bertha OS Irons promote more distance in an entirely new way, led by extraordinary light and strong Exo-Cage that allows us to strategically position weight to increase forgiveness, and helps our industry-leading, next-generation 360 Face Cup produce even faster ball speeds and more distance.

  • 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
  • Next-generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance
  • 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 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
