This cool long - sleeve hoodie is super easy to use. Just slip it on and you're good to go. Use the front pockets to keep your hands warm when it's cold or to carry small things like your phone or keys. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size so it fits you well. As for cleaning, you can simply throw it in the washing machine. Set the machine to a cold - water, gentle cycle and use mild detergent. After that, 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 your monitor. And because it's hand - measured, there might be a small 2cm/1 - inch difference in size.
