Our washed-denim work dungaree is flannel-lined for cold conditions. Made of 15-ounce, 100% cotton denim, it is lined with 4.5-ounce, 100% cotton flannel lining. It sits slightly below the natural waist, has a full seat and thigh, two utility bands and multiple tool pockets, a left-leg hammer loop and two reinforced back pockets. The 19-inch leg openings fit over boots and the main seams are triple-stitched for durability.
