The Portwest FR92 Bizflame Work Hi-Vis Contrast FR Trousers combine high visibility with protection against radiant, convective and contact heat and molten metal splash. They suit work where heat, flame and visibility hazards occur together, so one garment covers several risks.
The two-tone design pairs hi-vis fabric with contrast panels in the areas that pick up the most dirt. Six pockets, two-tier knee pad pockets and triple-stitched seams make them practical for demanding daily wear.
