Built for guys who work hard and love a good pair of jeans: Our Grit-n-Grind flame-resistant work jeans are made from lightweight, moisture-wicking, quick-drying denim with heavy-duty seams for durability and an arc-resistant button closure for an extra margin of safety. Designed with a bootcut so they're slightly tapered in the thigh area and wider from the knee to the hem so you can wear your favorite Timberland PRO® work boots underneath your jeans.
