The Portwest FR731 is an insulated bomber jacket for cold weather work where flame, heat and electric arc hazards are present. It combines several protective standards in one outer layer, so you can stay warm and protected without adding extra garments.
The cotton-rich Bizflame Work+ shell has a chemical-resistant finish, and a quilted flame resistant lining keeps in body heat. A front storm flap and elasticated side waist help keep cold air out, while four pockets and a sleeve pocket give you plenty of storage.
