Portwest FR440 Bizflame Work Hi-Vis Contrast FR Holster Trousers – Product Description

The Portwest FR440 Bizflame Work Hi-Vis Contrast FR Holster Trousers provide advanced multi risk protection for workers exposed to heat, fire, chemicals, electrical arcs and welding hazards. Constructed from Bizflame Work HV fabric, these flame resistant hi vis trousers combine durability, comfort and visibility for demanding industrial environments.

Twin stitched high visibility strips on the legs enhance visibility in low light conditions, while the strong brass front zip and reinforced seams ensure long lasting performance. The trousers feature interchangeable zip off holster pockets, allowing the wearer to customise pocket placement or remove them entirely depending on the task.

A practical multi pocket layout includes flapped front pockets, a flapped back pocket, a rule pocket and a lower tool pocket with flap. The elasticated back waist provides a secure and comfortable fit, and the hook and loop adjustable hems improve coverage over work boots. Two tier knee pad pockets allow adjustable knee protection for added comfort during kneeling tasks.

Certified to extensive flame resistant, antistatic, arc flash and high visibility standards, the FR440 trousers are suitable for petrochemical, utilities, fabrication, engineering, rail and general industrial sectors where reliable and comfortable FR protection is essential.
