These hip - hop style men's sweaters are super easy to use. Just slip them on like you would any other top. They're great for casual outings. When it comes to sizing, always refer to the size chart provided. If your body type isn't typically Asian, it's a good idea to go a size up. For maintenance, since they're made of cotton, you can machine - wash them on a gentle cycle. Use a mild detergent to keep the color and fabric quality intact. Avoid using bleach as it might damage the embroidery. Hang them to dry to prevent shrinking. These sweaters are fleece - thick, so they'll keep you warm and stylish at the same time.
