Like many vintage work shirts, our Short Sleeve Mechanic Shirt is made with sturdy 9.5-oz. cotton herringbone. With its alternating diagonal pattern, the durable fabric is quite supple. The half-zip front allows temperature regulation and is easy to operate while wearing light gloves. The center-rear box pleat provides ease of motion when working in tight spaces. Spread collar with neck closure button tab. Flapless button-close chest pockets.
