As tough as many jeans, Filson’s Clarkston Denim Work Shirt is built to stand up to long days on the toughest jobs, year after year. The 12.5-oz. 100% cotton denim will develop its own wear and patina, telling the stories of jobs done well. The chest pocket bottoms are reinforced with a second layer of denim for durability, and the back features dual shoulder pleats for ease of motion. Button-front and spread collar. Prewashed.
