A muscle vest, which some people call a muscle shirt, clings tightly like a t-shirt, but lacks sleeves. It lets you display the fruits of your workouts to admiring eyes. It also lets you move freely while lifting weights, running, or doing other active things.
Muscle vests in many attractive colours and printed with logos breathe well. They come in women's designs, too, either simple vests or body sheathes. Work out and show off in a muscle vest.
