Callaway Big Bertha OS HybridThe Big Bertha OS irons rank as Callaway’s most forgiving in its current iron lineup, and the same can be said for the Big Bertha OS hybrids, which were designed to be exceptionally easy to hit and launch without having to sacrifice distance

Callaway’s next generation Hyper Speed Face Cup is the key component in the distance generated by the Big Bertha OS hybrids, as it enables a clubface that delivers incredible ball speeds, even on off-center hits.

Additionally, a larger overall clubface makes the face more flexible for enhanced distance, while also inspiring confidence from players at address, and the use of a Boeing inspired Speed Step on the crown helps produce faster swing speeds.

Meanwhile, the higher launch that the Big Bertha OS hybrids produce is made possible by a low CG placement in what from a profile standpoint is a deeper overall clubhead, which also improves MOI by creating more stability at impact.

And finally, unique to the Big Bertha OS is that this is the only hybrid in the current Callaway lineup that features an adjustable hosel, which gives players the option to adjust loft by three degrees (+2/-1), as well as set the club up with either a neutral or draw bias. That combination of adjustability not only allows players to hit these hybrids the precise distances that they want but they can also better control trajectory and ball flight.

Big Bertha OS hybrids are available in men’s and ladies models in lofts of 19, 22, 25, 28, and 31 degrees. The stock shaft is the UST Recoil ES, but other options are also available at no upcharge.
