Callaway Men's Big Bertha Driver, Right Hand, Graphite, Stiff Flex, 9.0

Bertha's Back. And She's Meaner than Ever. The new Big Bertha Driver is so revolutionary, it deserves to carry one of the most legendary names in golf. It's faster, more robust and features our new Adjustable Perimeter Weighting for maximum distance via total driver performance. Don't just take our word for it. Go hit it. You'll see. Hyper Speed Face: Our New Hyper Speed face design is nothing short of groundbreaking -revolutionary - it's lighter (10% lighter), hotter (of course) and more robust than ever before, increasing ball speeds on shots hit across the face. Not that you would ever hit one anywhere but dead center. But if you did, it's nice to know we have you covered. Adjustable Perimeter Weighting: We put our new Adjustable Perimeter Weighting slide toward the rear of the club which leads to significantly higher MOI and forgiveness, while offering a wider range of draw and fade bias options. All that amounts to longer, straighter shots. And those are good things. Those are good things indeed. Forged Composite: High Strength, Lightweight crown saves 20g of weight, allowing Big Bertha to have Adjustable Perimeter Weighting, a deeper CG for higher MOI and low spin with a lighter, more preferred swing weight. The more adjustability you add to a driver, the more imperative it is to have a forged composite construction.
