The "Memphis Hero™" series is made of a high performance cut resistant material that achieves high levels of cut and comfort. The blended Kevlar®, stainless steel, and other fibers are used for general purpose work applications to provide cut and abrasion resistance when working with sharp objects. Some styles are stripped or dotted to provide a better grip and increase durability. The 93840 has an uncoated 13 gauge Kevlar®/Stainless Steel/Spandex fiber shell with an ANSI 4 cut score. This lightweight material gives you the cut resistance you need with outstanding fit, comfort, and breathability.
