This men's long sleeve performance shirt by Ariat has a bit more of a western flair than other shirts in the line. The black snap buttons and chest pockets with pointed flaps look handsome, no matter what work you're getting done for the day. This shirt is constructed of a new fabric with both SPF protection as well as unique moisture wicking properties to help you stay cool and dry. The inner yokes have nylon mesh panels to help keep the shirt sticking to you. Greater arm mobility is a new concept with work shirts, and this one features it. You will notice how easy it is to lift your arms above your head without strain on your shirt tails if they're tucked into your jeans.
