Give this men's Ariat performance shirt a try if you're looking for a smart looking western shirt with loads of comfort and compatibility for your day of hard work. The fabric is made of an SPF material that helps block the sun's harmful rays. The material also helps wick moisture from the body and dry it quickly. The nylon mesh panels at the inner yokes are ideal for pulling sweat from the back of the neck and collarbone. The arms are constructed in such a way that they allow greater movement than your typical shirt. You can reach and stretch all you want without worrying about pulling and tugging.
