Callaway have worked with the aerodynamics experts at Boeing to reach a completely new threshold of ball speed.
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 more MOI, a stretched out crown with a bigger footprint, and a Centre of Gravity that’s lower and deeper.

To make it faster, Callaway put in the distance technology from their completely re-engineered face and a lighter Speed Step Crown, and Boeing helped them make their most aerodynamic head shape ever. When they added all that together with lower spin and a more neutral CG bias into a 450cc head, the result was even better than they could have imagined.
