Cobra SS HyperSteel Offset. The Cobra SS HyperSteel Offset is designed for players looking for a forgiving oversize head generating superior distance and accuracy. Made of 17-4 stainless steel, the head has weight positioned low in the back of the clubhead for greater accuracy, distance, and higher trajectory. The offset head on this version makes it even easier to square the face at impact - resulting in straighter, more forgiving shots - ideal for slicers of the ball.
