Using this hoodie is as easy as it gets! Just put it on and enjoy the comfort. It's suitable for both men and women, so you can wear it casually or during the Christmas season. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because of the international sizing standard. As for maintenance, simply throw it in the washing machine with cold water, use a gentle cycle and mild detergent, then hang it up to dry. Be aware that the color you see on your monitor might not be exactly the same as the actual hoodie, and there could be a small measurement difference due to hand - measuring. That's all you need to know to make the most of your new hoodie!
