The Portwest BZ30 Bizweld Work FR Trousers are made for work around heat, flame and molten metal splash, including welding and allied processes. They are also tested against the thermal hazards of an electric arc, so one pair covers several risks.
The heavy 100% cotton fabric is built to last, with twin-stitched seams and a brass zip. Three pockets keep tools and small items close, and a half elasticated waist helps the trousers stay secure as you move.
