DuPont's remarkable Kevlar fiber is 5 times stronger than steel on an equal weight basis and is used in high performance products like bullet proof vests and infantry helmets. Superior protective Kevlar sleeves give exceptional cut resistance, without sacrificing comfort. The snug knit wrist keeps the sleeve comfortably in place. The body of the sleeve is woven and holds its shape; it won't slip or fall down the arm. Both wrist and body are Kevlar. They withstand rugged wear, and the high level of cut and slash resistance make them ideal for metal stamping, glass and other sharp-edged materials. Kevlar provides the added bonus of inherent flame resistance, so they will not melt or burn either. This is a great property for employees working around any heat, flames or sparks. Available in 7" (SLKW7) and 8" (SLKW8) length without thumbhole. 7" (SLKW7TH) length with thumbhole. Kevlar is a registered trademark of E.I. du Pont de Nemours and Company.
