PRODUCT FEATURES:
Callaway Women's Big Bertha Burner Driver

• Its 440cc titanium head, slightly longer shaft and strategically positioned center of gravity (CG) help you hit longer tee shots that find the fairway.
• Allows a woman to maximize her swing speed for increased ball speed and longer distance.
• Strategically placed internal weighting is biased toward the heel, helping golfers close the face more easily at impact to promote a draw ball flight and reduce slices or fades.
