Introducing the Big Bertha OS irons with revolutionary Exo-Cage club head construction. Designed to give more forgiveness and distance, with progressive centre of gravity for increased control.
Exo-Cage Construction & 360 Face Cup
This construction is lightweight and high strength and has allowed the engineers at Callaway to distribute more discretionary weight into strategic locations to promote more forgiveness. Plus next generation 360 Face Cup technology elevates club face COR closer to the USGA limit to produce even faster ball speeds and greater distance.
Tungsten-Loaded Standing Wave
This technology is located in the sole, which lowers the centre of gravity to promote a higher launch angle for even more carry distance. This also provides increased ball speed on shots hit low on the club face.
The Big Bertha OS Irons Feature:
- Exo-Cage Technology
- Tungsten-Loaded Standing Wave
- Next Generation 360 Face Cup
- 1-Year Guarantee & True Temper Speed Step 80 Steel Shafts
Progressive Centre of Gravity
To promote increased control, the irons have a progressive centre of gravity position. Each iron head from the highest to the lowest incorporates this technology to promote higher launch and long carry in the long-irons and increased control in the short-irons.
