The Cobra S3 Pro Irons combine two tour-proven irons into one set. The 3 to 6 iron feature the Cavity Back (CB) design, while the 7 iron to PW feature the Muscle Back (MB) clubhead. The Cobra S3 Pro is designed for the low-handicap golfer seeking improved control and workability. The CB long and mid irons benefit from a perimeter-weighted, cavity-back design that promotes a slightly higher launch and added forgiveness for consistently long and accurate shots. The short-irons feature the Muscle Back design that provides optimal shot-making and trajectory control. The entire Cobra S3 Pro Iron set have a soft satin finish to reduce glare, a finish that is the choice of Cobra's Tour staff.
