To use this hoodie, just slip it on like any other hoodie. 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 for a better fit. As for maintenance, you can easily machine wash it in cold water on a gentle cycle with mild detergent. Then, hang it up to dry. Be aware that the color might look a bit different on your screen than in person, and there could be a small measurement difference because it's measured by hand.
