The Cobra S3 driver features a 6-4 titanium head and face with an aluminum hosel sleeve. The Adjustable Flight Technology (AFT) provides three simple face angle settings, open, neutral, and closed, to optimize flight as well as improve accuracy and distance. The new E9 Face Tachnology creates a 30-percent larger Sweet Zone for improved distance, forgiveness, and accuracy. The elliptical shape of the E9 optimizes ball speeds in the areas that golfers hit most often--high in the toe, and low in the heel. Its beveled perimeter reduces wall thickness around the face, allowing for more weight to be repositioned lower and deeper in the head for optimal launch angles.
