With a look like denim, it’s no wonder chambray’s so popular. But there’s one big difference between the two fabrics: chambray isn’t a twill so it’s naturally lighter — and perfect for all seasons. Lighter doesn’t mean flimsy, however: it spent decades as the fabric for work-duty shirts in the U.S. Navy, where toughness isn’t optional. Ours has strong triple-needle stitching at the shoulder, arm and side seams. Long sleeve. 100% cotton. Machine wash. Imported.
