Hey, when you're spending the better part of your day pushing earth with a Caterpillar you don't exactly go in for those fancy embroidered polo shirts. These shirts have been very popular on construction job sites, although those guys tend to cut the sleeves off! And then there are those guys that like to rub it in the face of the rest of us, and wear their "Official Work Shirt" to the beach, the marina, Home Depot on the weekend. You get the picture. If you're out in the direct sun, you might want the white or ash colored shirts.
