I bought this coat and have never worn it so parting with it. These coats are in high demand and often sell out. This is a thick navy 100% cotton duck with herringbone detail. From the LC King website: Our chore coats exemplify the history of American perseverance through four generations of wear testing. Factory built in a rigid 12oz navy duck from our friends at Mount Vernon Mills in Trion, GA. They’ve been weaving quality fabrics since 1847 with a passion for perfection. We build strength & durability into each garment to exceed our customers’ expectations. For years to come, this piece will be a reliable standard for each job and every occasion. Built For Life. Built To Last.
