This collared, long-sleeved shirt is nice enough for Sunday dinner but tough enough for a Monday morning on the line. It's made with 5-ounce, yarn-dyed 100% cotton chambray. Cotton is one of nature's most versatile fabrics, tough enough to stand up to wear and still feel comfortable against your skin. Cotton is also breathable, and that's important when you're working. The airy material of this western shirt lets out hot air and lets the cooler stuff can flow in.
