This hoodie is really easy to use. Just put it on like you would any other hoodie. The front pockets are handy for keeping your hands warm in cold weather or storing small things like keys or your phone. For sizing, remember to order 1 - 2 sizes bigger than your normal size because the international sizing is a bit smaller compared to the USA standard. When it's time to clean your hoodie, use a washing machine. Set it to a cold - water, gentle cycle and use mild detergent. After washing, hang it up to dry. Also, don't be surprised if the color looks a little different on your screen than in person because of monitor settings. And there might be a small difference in the measurements due to hand - measuring, about 2cm/1 inch.
