Using this hoodie is easy. Just put it on and enjoy the comfort and style. When you feel cold, you can put your hands in the front pockets. If you're going out, you can keep small items like keys or your phone in them. For sizing, remember to order 1 - 2 sizes bigger than your normal one because of the international sizing difference. When it comes to maintenance, machine wash it in cold water on a gentle cycle with mild detergent. After that, just hang it up to dry. Also, don't be surprised if the color looks a bit different from what you see on your screen because of the monitor. And there might be a small measurement error due to hand - measuring.
