Carhartt flannel lined pants take on the cold weather in greater comfort. The dungarees are made of 12-ounce, 100% ring-spun cotton duck, lined in 100% cotton flannel, sit at the natural waist, and are cut with a full seat and thigh. There are multiple tool and utility pockets plus a hammer loop and reinforced back pockets. The 19-inch leg openings are sized to fit over work boots.
