These women’s flame resistant trousers are made for work involving heat, flame, welding and electric arc hazards. They combine several types of protection in one garment, so you can wear a single pair across varied tasks on site.
The 350g fabric is built for daily wear, with triple-stitched seams and reflective tape that is double stitched in place. Knee pad pockets, a rule pocket and adjustable hems make them practical for kneeling, measuring and active work.
