The Portwest FR58 is an insulated flame resistant bib and brace built for the demands of offshore work in cold weather. A Bizflame Work cotton outer is paired with flame resistant padding and a flame resistant cotton lining to trap heat and keep you warm.
It is made for practical daily wear. Side leg zips open the legs wide, so you can pull the garment on over large boots. Reflective strips on the legs help you stay visible, and triple stitched seams add strength where it matters.
