    Features & Benefits

    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 Senior Irons is rated 4.8 out of 5 by 4.
    Rated 4 out of 5 by from These irons have a great, clean look. Very easy to hit. After playing Callaway Fusion Wide Sole irons for years, I was apprehensive about making a switch. The Callaway Senior OS irons are exceptional to say the least. They have a great top line look and when the ball is hit have a great feel as contact is made. I'm glad that I made the change.

    Rated 5 out of 5 by from Longest club I have ever had 1ST competitive round with my regular group, an 80. I was 2 clubs longer than my normal rounds. The forgiveness was impeccable. Made them look for the entire round. If a couple of more birdie putts hadn't burned the edges would have been a 77. I am excited about my next round. The guys were texting me the next day wondering where I purchased them, looks like they may be trying to trade up. I would recommend these to anyone who wants a better game.

    Rated 5 out of 5 by from New kind of iron I originally ordered the Senior OS 6 thru PW set. After several rounds I saw what these irons could do and I then ordered the 5 iron. Had to order the Senior model on-line because none of the stores have the Senior model. You get exactly what you want from Callaway and dont have to settle for whatever the ordinary golf shops have in stock.

    Rated 5 out of 5 by from GREAT CLUBS BUT OH THOSE HYBRID COVERS I bought 4-7 hybrids and 8-S irons. Great clubs, even though I never buy the hype that clubs will improve your game I think these have. Love em. Only downside is you pay that kind of money for clubs and they give you head covers for the hybrids that are well lets just say garbage. If the covers last 6 months I will be amazed.
