Big Bertha OS Hybrids are designed for super-charged distance and ultimate forgiveness, with a deeper body, larger and faster face, and next-generation Face Cup technology.
Explosive Distance from Next-Generation Hyper Speed Face Cup
Next-generation Hyper Speed Face Cup promotes faster ball speed across the face, especially on off-center hits.
Larger and Faster Face for More Ball Speed
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.
Faster Head Speed for More Distance from Speed Step Technology
Designed with the assistance of aerodynamic experts, Callaway’s Speed Step Technology improves airflow to promote faster clubhead speed for more distance.
