The Portwest FR26 Bizflame Work FR Trousers are multi-norm protective trousers for welding, hot work and jobs with electric arc risk. They protect against radiant, convective and contact heat and molten metal splash, and they are suitable for wear in ATEX environments.
Reflective strips on the legs improve visibility, and triple-stitched seams add strength for demanding daily use. Six pockets, including knee pad pockets and a rule pocket, keep tools and kneeling protection close at hand.
