    Technology Specs

    Big Bertha OS Irons Technology Item
    • 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.

    • 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.

    Big Bertha OS Irons is rated 4.7 out of 5 by 73.
    Rated 5 out of 5 by from All categories rated are an improvement Ball flies off the face faster, straighter, farther, higher. Best new club I have ever purchased. Only flaw is the face loses it's color quickly from use.

    Rated 5 out of 5 by from This is a Quality product. I have played Callaway clubs for years. I feel these are the best irons I have ever played with. I hit them straighter. I have gained about half a club in distance. It feels great when you hit a solid shot. I also have more confidence over the ball. You still have good days / bad days. You still have to hit the shot. These are High Quality irons. Sorry Callaway, I do not intend to buy another set of irons. My wife will probably be happy about that.

    Rated 5 out of 5 by from Great Service Bought "like new" Big Bertha OS irons 6-9, PW & AW and they are the best irons I have ever hit. I had an interaction with CSR Ester and she was very helpful solving my issue on one of the irons. I would definitely recommend Callaway Pre-owned to anyone looking for good quality used clubs.

    Rated 5 out of 5 by from Great set of Irons After 30 days, I have adjusted to the new set and for someone who has not played in 20+years, these clubs brought my game back. It will be awhile before I get the true results, but my accuracy and distance were noticeably better than with my old clubs.

    Rated 5 out of 5 by from Great irons Very solid looking and acting irons. I did not experience the increase in distance that other reviewers did but still very happy with my upgrade to GBB irons

    Rated 5 out of 5 by from Great set of irons Solid feel, set up well to target line for me. By far the easiest to hit irons that I tried, i.e. titleist, taylormade, cobras. This is my second set of irons purchased from callaway preowned.
