This jacket was an XL, but I accidentally shrunk it and now it fits closer to a Small according to the measurements on the Sidnaw Company website. MEASUREMENTS: Chest, center pit to pit - 18" Chest, bottom pit to pit -22" Length - 24" Sleeve - 22.75" Waxed canvas is a 100% cotton material that has been impregnated with natural waxes top to bottom. This increases resistance to wind, water and cooler temperatures. Our work jacket features a tilted chest pocket for easy access and deep hand pockets that are sure to keep your belongings from falling out. Each raw copper rivet is backed with a leather washer to increase durability
