The Portwest BZ443 Bizweld Work FR Trousers are built for work where electric arc, molten metal splash and heat are part of the job. Their flame resistance is guaranteed for the life of the garment, so protection holds up wash after wash.
An elasticated back waist keeps the trousers in place as you bend and kneel. Six pockets give you room for tools and small items, and reflective trim helps you stay visible.
