Forged from soft 1025 carbon steel, the Cobra S3 Pro Irons are two sets in one. Long and mid-irons (3- through 6-iron) are cavity-back weighted for forgiveness. Short irons (7-PW) sport a muscle-back design for workability and trajectory control. All of the irons feature a glare-reducing, soft satin finish – the preferred look for many PGA Tour players.
