Our popular Washed Duck Work Dungaree also comes in a plaid flannel-lined version for extra on-the-job warmth. It provides all the usual good things like extra room in the seat and thigh. Plenty of utility and tool pockets. A hammer loop. And big 19-inch leg openings to fit over any work boot. But this dungaree is lined in 100% cotton flannel to take the chill out of cold weather. Available in four colors that coordinate with Carhartt shirts, sweats, jackets and vests
