For the XR 16 Ladies Driver, Callaway Golf worked with the experts at Boeing to redefine the boundaries of possibilities of ball speed and aerodynamics. Callaway Golf and Boeing conspired to engineer their most forgiving shape ever and made it even faster with a re-engineered Speed Step Crown.This thing is big and fast like you wouldn’t believe, with a high speed head and lower drag in the crown that, as you can guess, is going to add some serious ball speed. It’s extremely forgiving from the larger shape for greater MOI, and it has a stretched out crown with a bigger footprint, and a Center of Gravity that’s lower and deeper.For more ball speed all across the face, Callaway Golf we added their next generation R*MOTO face that’s lighter and up to 19% thinner. And of course, you can choose from a wide selection of custom shaft options to fit your swing speed.If you want the ultimate in ball speed?
