Big Bertha Fusion pushes the boundaries of forgiveness like no Callaway club ever has. The key benefit? More forgiveness means straighter flight on mis-hits, and straight flight nets longer distance, drive after drive.
To increase forgiveness you have to raise the head’s MOI measurement. We’ve succeeded dramatically by developing a revolutionary clubhead design that starts with an aerospace-grade titanium exoskeleton called an Exo-Cage™. The Exo-Cage is fitted with a crown and sole composed of an ultra-light, ultra-strong material called triaxial carbon. Triaxial carbon is made possible by the deep knowledge we’ve gained from our years of experience incorporating carbon materials into our metalwoods.
Big Bertha Fusion’s numbers speak volumes. The revolutionary new triaxial carbon material is over 65% lighter* than titanium, and more than 35% thinner than our previous forged composite material. This allows us to position a remarkable 35.4 grams** in strategic areas of the head to optimize the center of gravity and increase the MOI by up to 17%*** — a remarkable jump that golfers will notice by increasing the quality and accuracy of their off-center hits.
This driver also incorporates Callaway’s Speed Step technology, devised with the help of aerospace experts, to enhance the head aerodynamics, promoting faster clubhead speeds.
Features:
Fusion Technology For Maximum Forgiveness
- Fuses a titanium EXO-CAGE with an ultralight triaxial carbon crown and sole to create forgiveness and stability, promoting straighter and longer drives
Innovative Exo-Cage For Forgiveness & Power
- Titanium EXO-CAGE makes it possible to reposition weight for more forgiveness and increased swing speed to increase accuracy and distance
Industry-leading Aerodynamics For More Head Speed & Distance
- Our proprietary Speed Step, designed with help from aerospace experts, reduces drag to promote faster swing speed for more distance
High-Performance Shaft Options For Power & Control
- Choose from UST’s first ever Recoil shaft in a driver or the new 60g Mitsubishi Diamana Red Board, both are designed for more distance and accuracy

Pre-Owned Club Conditions
Condition: Like New
Shows virtually no traces of wear, may have been hit one or more times in controlled conditions. May show signs of very minor "shop wear" (i.e. a single cosmetic blemish), but still full of NEWNESS!

Condition: Excellent
Clubs have seen minimal usage and are in top of the line preowned condition. You may see some minor or faint cosmetic blemishes (i.e. very light scuffing and/or scratching). Typical wear that you will see on an Excellent condition club is normal ball marks that are lightly visible on the face, minimal scratching to the crown, sole and edges. Shaft has no noticeable wear.

Condition: Very Good
Clubs have seen normal usage for an extended period of time or at least one season, the wear you’ll notice will be typical of the age of the model. All of the wear is purely cosmetic, and will not in any way affect the performance of the club. Typical wear you’ll see on a Very Good condition club is normal ball marks and scratching on the face, normal scratching on the sole, faint dings and nicks on the crown and/or around the edges of the head, light scratches, paint chips, paint blemishes on or around the crown. Shaft has minimal wear.

Condition: Value
Clubs offer a great value for someone who isn't as interested in cosmetics, but cares about performance. Shows frequent to heavy use, but does not show any signs of abuse.
