Good condition Preowned 100 % But these flame-resistantt coveralls do more than just keep you safe. They also keep you working comfortably and efficiently so you can focus on the job at hand. They're unlined and made from 9-ounce, flame-resistant 100% cotton twill, so these navy blue coveralls won't weigh you down. The leg openings fit easily over work boots, so you can pull them on and off quickly. The bi-swing back and pleated elbows give you freedom of movement, allowing you to twist and turn and work hard without feeling restricted. It's bad enough if your boss is chafing your backside. You don't need your FR coveralls to do the same thing. They also feature a spread collar, and the triple-stitched main seams means these Carhartt coveralls are durable.
