This men's hoodie sweater is super easy to use. Just put it on and enjoy the comfort. When it comes to sizing, remember to order 1 - 2 sizes bigger than your normal size because of the international sizing standard. For cleaning, simply toss it in the washing machine with cold water, set it on a gentle cycle, and use mild detergent. After that, hang it up to dry. Keep in mind that the color you see on your monitor might be a bit different from the actual product, and there could be a small measurement error because it's hand - measured. That's all you need to know to take good care of this awesome hoodie!
