The Ariat Rebar Durastretch Flannel Men's Work Shirt is a great choice for men who need a shirt that will provide them with both comfort and mobility. The hidden sunglasses cloth is a great feature, as it allows you to keep your glasses clean and safe while you work. The button cuffs are also a nice touch, as they help to keep the sleeves in place while you're working. The Greater Arm Mobility seam construction is another great feature, as it allows you to have maximum range of motion. The stretch flannel provides both softness and strength, and the 97% cotton, 3% spandex fabric blend ensures that the shirt will be durable and comfortable.
