Golfballs.com Expert Description

Extend your set and enhance the variety of shots you can take with the Callaway Golf Big Bertha OS Graphite Combo Set that includes both Big Bertha OS irons and hybrids. Irons contain elements including Exo-Cage to shift weight and produce more forgiveness, as well as a 360 Face Cup design for faster ball speeds, while the hybrids contain features like a Hyper Speed Face Cup and Dual Runner sole design to help you achieve more distance.

Big Bertha OS Graphite Irons

Lightweight yet strong Exo-Cage allows weight to shift into more effective positions on the club head to produce more forgiveness, allowing players to see distance even on mishits. The 360 Face Cup works in combination with the Exo-Cage to raise COR close to the legal limit set by the USGA, and to produce faster ball speeds off impact.

A tungsten-loaded Standing Wave in the sole progressively lowers the center of gravity in each club, optimizing the launch angle to enhance performance on each iron. Long-irons have higher launch angles for longer carry, while the short-irons have improved control over shots. Each iron also comes standard with the UST Mamiya Recoil ES 460 graphite shaft for lighter swing weight.

Big Bertha OS Hybrids

For explosive distance, the Big Bertha OS Hybrids contain an updated Hyper Speed Face Cup in a larger and more flexible face, which generates impressive speeds no matter where impact occur, including areas off center. Not only is the hybrid faster, it’s more forgiving thanks to a more refined and sleeker head design that creates more length head-to-toe, as well as a deeper body that raises MOI for enhanced stability.

Dual Runner sole design improves turf interaction, helping you achieve a more solid strike each time. Each hybrid also comes standard with the UST Mamiya Recoil ES 460 graphite shaft, perfect if you have a slightly slower swing speed.

Features of the Callaway Golf Big Bertha OS Graphite Combo Set:

• More forgiveness and ball speed from new exo-cage technology
• Even more ball speed from next gen 360 face cup
• Higher launch for longer carry from tungsten-loaded standing wave
• Progressive center of gravity for increased control
