Why Buy?

Big Bertha OS Senior Irons are lighter in overall weight, with more loft to promote faster ball speed and higher launch angle to make it easy to get the ball in the air. Get 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.

    Technology Specs

    Big Bertha OS Senior Irons Technology Item
    • 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.
