Using this hoodie is super easy. Just put it on and zip up or down depending on how you feel. The front pockets are great for keeping your hands warm or storing small things like keys or your phone. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because the international sizing is a bit smaller. As for maintenance, throw it in the washing machine on a cold, gentle cycle with mild detergent and then hang it up to dry. Keep in mind that the color might look a little different on your screen than in real life, and there could be a small measurement difference because it's measured by hand.
