The Nike VR Pro Cavity irons inspire confidence and are designed for players who desire more distance and forgiveness than Nike forged irons. The long irons (through the 5 iron) feature a 3-piece construction with an AM355 face, Opti-Mass tungsten/resin insert, and a 17-4 stainless steel body, resulting in higher launch angles and explosive distance. The mid irons (6-8 irons) feature the Opti-Mass tungsten/resin insert and a 17-4 stainless steel body and face, resulting in higher launch angles and improved distance control. The short irons are a one-piece 17-4 stainless steel head for optimal trajectory and distance precision.
