The vented back on the Wolverine shirt is specifically designed to keep you feeling cool when things start heating up. This portion has a 100% polyester mesh underlay. The short sleeve shirt is great for work or play, as it provides lightweight coverage. It weighs just 3.5 ounces, or 120 grams. The 100% cotton poplin is used because it'll make sure you stay comfortable all day. Since the material is peached, that means it's been treated to make sure it's soft and smooth for you. The unique Trailhead short sleeve design has rolled shoulders to provide you with ease of movement, and a button down collar gives you that well put together look. There are two chest pockets, also made of the sturdy cotton poplin, and these have center pleats and flap closures to secure your belongings. The back yoke of the men's workwear has an embroidered claw logo for a quick way to show off your favorite brand, and fogged plastic logo buttons with colored rims finish off the entire design nicely. Material: Cotton.
