The Nike VR Pro Cavity Irons are a progressive set which feature Nike’s Opti-Mass Weighting System. The short irons from 9 to sand iron are a one piece design. The 6 to 8 iron are a two piece design and the longer 4 and 5 irons are 3 piece. The VR Pro Cavity heads have a larger cavity that is filled with a the Opti-Mass insert. This is an injection-molded blend of polymer and high-density tungsten to create precise weight distribution and more predictable distance, as well as being a vibration dampening tool.
Each head is features Linear CG Mapping where the centre of gravity moves gradually and consistently throughout each golf iron. This allows the centre of gravity to be adjusted through the set for conistent distance and trajectory and what Nike promises is ‘explosive distance with the trajectory required for tour like golf shots.’
