With E9, Cobra optimized each club in the S3 Irons set to match the strike patterns most common with that club. In the long irons, for example, Cobra says the strike pattern is elliptical, stretching horizontally on the iron face. The pattern becomes oval in the mid-irons, and circular in the short irons.
The purpose of the E9 tech, the company says, it to match the "Sweet Zone" of each iron face to that strike pattern.
The Cobra S3 Irons have hyper-steel faces with a progressive cavity design; a hidden internal polymer topline (affecting weighting characteristics); and stepped, crescent (mid-width) soles that narrow in the toe and heel to improve turf interaction.
The Cobra S3 Irons come in 4-SW for men (senior and women's set are 5-SW). Shaft options include the Aldila NV-3 graphite and Nippon NS Pro 103H steel. The MSRP with graphite shafts is $875, or with steel $745.
In addition to the base Cobra S3 Irons set, also available is an iron-hybrid configuration. The Cobra S3 Iron-Hybrid set is for the golfer who prefers hybrids to long irons. It comes with three Baffler-style hybrids in place of the 3-, 4- and 5-irons, plus 6-PW S3 irons, all with graphite shafts.
Another option is to get steel shafts in 5-PW, plus graphite-shafted 3 and 4 hybrids. Senior and women's S3 Iron-Hybrid sets have 4-6 hybrids plus 7-SW irons. The Cobra S3 Iron-Hybrid set has an MSRP of $1,000 with all-graphite shafts; or $875 with steel shafts in the irons. cobragolf.com
