OVERVIEW: The VR-S irons are constructed of high-strength, ultra-thin stainless steel with NexCOR variable face-thickness technology. The VR-S clubface delivers a high COR face for more distance. The new face construction expands the maximum COR zone around the middle and lower area of the face. Nike's PowerBow technology produces a faster, higher launch for maximum carry, straighter ball flight and steeper descent to hold greens.
