Emerald CX is Superior Glove's engineered blend of super-strong materials, combining some of the strongest fibers known to man: stainless steel, Kevlar and stainless steel mesh. Besides their cut resistance, the best thing about these gloves is that they don't feel like highly cut-resistant gloves, which is amazing when you consider that you're wearing a quarter mile of steel on your hands. This model features a fine, highly flexible, cut-resistant mesh layer between the glove body and the nitrile palm coating. This layer is barely noticeable, yet it withstood 3800 grams (palm only) of force in lab trials. Compare that to a heavyweight leather glove, which cuts at under 150 grams.In addition to stellar cut resistance, high abrasion resistance and exceptional comfort, Emerald CX is where value meets performance; you would expect to pay a lot more for a glove with such impressive stats. Test them in your own demanding applications!Kevlar is a registered trademark of E.I. du Pont de Nemours and Company.
