Our fire-resistant (FR) duck canvas is the perfect base for this classic workwear item. Our FR welder’s bib is constructed using tough flame-resistant fabric, reflective tape, zippers, and buckles to reduce worksite risks. The rugged FR canvas, double knees, triple needle construction, reinforced crotch, and bartacked stress points ensures this FR Overall will last shift after shift and year after year. Ditch the leather and denim, and move into something that will last longer than a month at a time.
