The Women's Big Bertha OS Combo Sets features game-changing distance and ball speed in the irons from a revolutionary new EXO-CAGE and 360 Face Cup, with explosive forgiveness and ultimate forgiveness in hybrids that are super easy to launch.
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.
Next-generation 360 Face Cup technology elevates clubface COR closer to the USGA limit to produce even faster ball speeds and more distance.
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 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.
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.
Next-generation Hyper Speed Face Cup promotes faster ball speed across the face, especially on off-center hits.
A larger and more flexible face helps in two ways: 1) The added size gives you more area to make contact with. 2) The added flexibility pushes the COR closer to the USGA limit, promoting faster ball speed for more distance.
Refinements to the head design include: 1) Longer heel-to-toe length that allows for a larger and more forgiving face. 2) Deeper body for increased MOI and stability. Together they make the BBOS hybrid remarkably easy to hit.
The Dual Runner Sole design promotes better turf interaction for more consistently solid contact.
Big Bertha OS Irons incorporate a revolutionary clubhead construction, called the Exo-Cage, that promotes more distance in an entirely new way. Callaway Big Bertha OS Irons: Specs | Availability | Photos | 3D Images
