The Callaway Big Bertha V Series fairway woods are all about velocity. By using lightweight materials and an aerodynamic design, Callaway has taken the return of Big Bertha and made it faster. As in faster club speeds and ball speeds that add up to more distance. The lightweight design is made more versatile with the addition of the modern warbird sole plate. This classic sole design with heel and toe relief helps the club sit square off the tee box and helps cut through tough lies everywhere else.
