What sets an ordinary t-shirt apart from a sports t-shirt and why is it worth exercising in clothing designed for that purpose? It's primarily about material and cut. Thanks to quality material, a sports t-shirt will wick away sweat, will be comfortable against your skin and thanks to its cut won't pinch or pull anywhere. Such a t-shirt is then very easy to care for and moreover really dries quickly, which you'll appreciate with frequent washing.
