Key to the Cobra S3 is E9 Face Technology, providing a ‘Sweet Zone’ that starts in a wider elliptical shape in the long irons, and progresses to a circular shape in the short irons.
The unusual two-tone finish works really well at address. However, the cavity design makes the head difficult to clean.
For a club with a cavity and weighting in the back of the head the Cobra S3 looks great behind the ball. The look creates the impression you can do anything with the ball and the flights is powerful.
