The MidwayUSA Men’s Level One Base Layer Long Sleeve Shirt is your first line of defense against cooler weather. Made of a polyester/spandex blend, this next to skin layer has a snug fit and wicks away moisture. Flatlock seams lay flat to prevent chafing. Silvadur™ Antimicrobial treated material uses silver’s elemental powers and a patented delivery system to reduce odor-causing bacteria. Perfect for those early season days when an insulated layer is too much, but you need something more in that first or last hour of the day. Great as a first layer later in the season, too.
