We Built a Cage and Unlocked More Distance. 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.

Features:

More Forgiveness and Ball Speed from New Exo-Cage™ Technology

  • Positions more weight in strategic locations to increase forgiveness and helps our next-generation 360 Face Cup function more efficiently


Even More Ball Speed from Next Gen 360 Face Cup

  • Elevates clubface COR closer to the USGA limit to produce even faster ball speeds
  • Big Bertha OS Irons


    Higher Launch for Longer Carry from Tungsten-Loaded Standing Wave

  • Technology in the sole lowers the center of gravity to promote higher launch for longer carry and more ball speed low on the face

  • Progressive Center of Gravity for Increased Control

      • Moving the CG location progressively lower in each head promotes higher launch and long carry in long-irons and increased control in short-irons
      • Big Bertha OS Irons


    Women’s and Senior Models

  • 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

    Happy Golfer
    Big Bertha os senior set is awesome. Balls go straight and further. About 7 to 10 yards. The 4 iron feels a little chunky. Like the way the clubs looks and feels. Hopefully my game will improve
    ProsForgiveness and length. Who wouldn’t want more distance and forgiveness.
    ConsExpensive. Thanks to Rock Bottom price it was affordable.
