This men's 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 one so it fits well. As for care, simply toss it in the washing machine with cold water 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 screen might be a bit different from the actual sweater, and there could be a small measuring error.
