This men's hoodie sweater is super easy to use. Just put it on and enjoy the comfort and style. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size for a better fit. As for care, you can machine wash it in cold water using a gentle cycle and mild detergent. After washing, hang it up to dry. Keep in mind that the color may look a bit different on your monitor, and there could be a small measurement inaccuracy because it's hand - measured.
