The Portwest FR66 Bizflame Industry FR Trousers are multi-norm protective trousers for hazardous work, both off-shore and on-site. One garment covers flame, heat, arc, static and light chemical spray risks, so you can meet several hazards with a single pair.
The cotton-rich Bizflame Industry fabric is built to stand up to industrial laundering. It also handles domestic care. Practical details include eight pockets, adjustable knee pad positions and a leg length you can extend as needed.
