Track pants are made of polyester materials that are smooth and wrinkle free. Mens tracksuit bottom are track pants which are loose pant usually worn for track events. It also comes with zipper near the ankle for ease in wearing and removing.
Sweatpants are like a sweatshirt for your legs. The bottoms of these are exactly made how the cuffs of your sweatshirt are made. These I prefer more because they have dope designs and patterns.
