These sweatpants are super easy to use. Just put them on like you would any other pair of pants. For the best fit, check the size chart before buying. When it comes to maintenance, you can machine - wash them in cold water. Use a mild detergent and avoid using bleach as it may damage the fabric. Hang them to dry to keep their shape. You can wear these pants for various daily activities like going for a walk, running errands, or just lounging at home. Just make sure not to wear them for extremely strenuous activities that might cause excessive stretching of the fabric.
