Pyrolon® was tough, but Pyrolon® XT is tougher! More durable too. These flame retardant coveralls from Lakeland feature a set-in sleeve design meeting ANSI/ISEA 101-1996 so you can move about easily and not worry about rip-outs. 70% stronger than Pyrolon® Plus 2, these garments are reinforced with a Cerex® Nylon scrim and a repellent finish, exceeding NFPA 701. Our Pyrolon® XT wear is air permeable with very high MVTR's. They can be worn comfortably over Nomex® or Indura® FR garments to help keep grease and grime off of the more expensive coveralls. Coverall features collar and zipper front. Blue/Gray color. Meets or exceeds ANSI 101-1996 sizing requirements. Sizes: Small thru 5XL. 25 per case. Sold by the case.
