The new men\'s Cobra King Speedzone Extreme driver is built to give you maximum forgiveness with maximum distance even when you do not hit the ball right out the middle of the clubface. It gives you a much straighter, more consistent trajectory. The head has a slightly larger shape profile than the Speedzone driver which is also part of this collection. A 17-gram weight in the head gives you a higher MOI (Moment of Inertia) which enables you to have a faster clubhead speed which equals more distance.
