Let the real you come through. And by you, we mean sweat. This 15% cotton / 85% polyester blend feels like your favorite worn in t-shirt yet wicks moisture away like none you've worn before. Made with Dri-Release with the natural odor neutralizer, Fresh-Guard, even when the sweat comes through, the shirt will smell like it just came out of the wash. Because Fresh Guard is a bacteristat, it creates an environment in the fabric that bacteria will not thrive in and keeps bacteria growth from happening to begin with. In short, it doubles as a great undershirt when you run out of deodorant.
