These men's high - street sweatpants are a great addition to your wardrobe. To wear them, simply put them on like regular pants. The elastic waist ensures a comfortable fit. When it comes to sizing, always check the size chart as different suppliers have different standards. If it's Asian size, go for a larger one. For maintenance, machine wash them in cold water with similar colors. Avoid using bleach as it can damage the polyamide material. Hang them to dry to keep their shape. You can also iron them on a low - heat setting if needed. The side pockets are not only stylish but also useful for carrying small items like your phone or keys.
