Nike VR_S Covert irons
The name Covert is all about cavity backs and perimeter weighting (hence the red-headed Covert metalwoods with the center portion of the sole removed).
Nike VR_S Covert irons have a pronounced cavity and are intended to be super-game-improvement irons; MSRP is $699.99 (eight irons, steel shafts) or $799.99 (eight irons, graphite shaft). Distance is enhanced with NexCor face design.
The new X3X groove pattern in the irons' faces moves the grooves closer together for additional shot control.
