Trousers with outstanding strength to weight ratio. The fabric is inherently flame retardant, which means that the flame retardant properties are naturally present in its fibres. The trousers have CORDURA®/Kevlar®/Protal® reinforced panels on the knees. They feature many smart pocket solutions designed to meet certification standards. Pockets subject to excessive wear are reinforced with double thickness to extend their life. The trousers have nail pockets, an open ruler pocket and flapless rear pockets.
