Flash Face SS21

Callaway R&D has advanced its face architecture further in the Big Bertha B21 driver. This led to a change in face materials TA-15 which is lighter and stronger than traditional Titanium which still maintains the integrity of the driver structure. The Flash Face SS21 provides ultra-fast ball speeds across a more expansive area to deliver more distance performance.

T2C Triaxial Carbon Crown

This proven T2C triaxial carbon crown construction allowed Callaway engineers to position more weight in the perimeters for a higher MOI and more forgiveness, easy launch and long straight distance.

Jailbreak Technology

Jailbreak is another proven technology which dramatically enhances distance by stiffening the body to transfer more energy to the ball. The key structural components of a driver are the crown, sole and face each bend, flex and rebound at impact. Jailbreak Technology creates a remarkably efficient relationship between these components, thanks to two ultra-light titanium bars behind the face, to promote more ball speed across a much larger area of the face.

Big Bertha Profile

Big Bertha has always provided a large and forgiving profile. The B21 still has a large oversized head which specifically engineered with internal draw bias weighting to help promote a straighter ball flight. Its also has an ultra-low forward CG for low spin providing distance and to give you a more consistent ball flight down the fairways.

The Callaway driver comes complete with a matching head cover.
