Portwest FR410 Bizflame Rain+ Yellow/Navy Hi-Vis FR Overtrousers is designed for daily work with a clearly defined function.
The breathable ripstop shell combines polyester, modacrylic, cotton and carbon fibre with a PU coating. Flame-resistant reflective tape, UPF 40+ and a fully elasticated waist support visibility and easy dressing.
These trousers belong in a complete assessed protective system and Portwest recommends pairing them with FR605. Arc, welding and chemical ratings require correct combination, closure and care.
