    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.

    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.

    Rated 5 out of 5 by from Great iron As we get a little older our sweet speed slows down but with the Senior os irons you get still hit the same distance if not more! Bought pw thru 6 iron bit after playing a few rounds decided to buy a 5 iron .

    Rated 5 out of 5 by from Can hit a 4 iron again Had to stop playing 3 years ago due to nerve damage to foot- 11hdc; never better than 8hdc Am physically very active but found at 70 my swing speed dropped 8-10 mph with driver. I can hit a 4 iron 165 in the air from fairway or light rough; easy to hit; sound and feel great (Recoil graphite shafts) A Ping guy as a lefty, most of my life; but like these better than G700.

    Rated 5 out of 5 by from Excellent Clubs for Senior Golfers Because the lofts are a few degrees weaker does not mean that these irons will not give you the distance that senior golfers want. In fact, when you hit these irons you will find a players iron feel at impact and the distance is far more than you would expect based on the loft of the iron you are using. I clearly did not expect this feel from a super-game improvement iron. Thank you Callaway for the excellent design and feel of these clubs. An added benefit is that these irons are much easier to hit even with a slow swing speed and the golf ball definitely gets airborne and flies toward the target whether it be the green or a lay up point on a long par 5 hole. I am 76 and I definitely recommend these irons for senior golfers.
