How to use this kid's zip - up hoodie is really simple. Just have your child put it on like any other hoodie. The zip - up design makes it easy to wear and take off. You can let your kids use the side patch pockets to carry things like keys, coins, or small toys. When it comes to maintenance, always remember to machine wash it in cold water with similar colors. This helps keep the fabric and the print in good condition. Avoid using bleach as it can damage the fabric and fade the colors. After washing, tumble dry it on a low setting. Do not iron the hoodie as the heat can affect the fabric and the print. Also, skip dry - cleaning because the chemicals used may not be good for the fabric. When you're looking at the size guide, keep in mind that the measurements are for when the hoodie is laid flat, and the actual size on your child might vary a bit.
