In addition to being fire-resistant, these versatile work jeans also have moisture-wicking and quick-drying properties to keep you cool and comfortable. They feature the classic look of a bootcut with a slim fit, hip pocket embroidery, contrast stitching, and the five-pocket styling that's signature to Wrangler jeans.Certifications vary by wash.
