Using this jacket is easy. Just zip it up and you're ready to go out and face the cool spring or fall weather. When choosing a size, make sure to check the size chart carefully as different suppliers may have variations. As for maintenance, you can machine - wash it in cold water on a gentle cycle. It's best to use a mild detergent. Avoid using bleach as it may damage the fabric. After washing, reshape the jacket and lay it flat to dry. Hang it up when it's completely dry. Also, don't iron it on high heat as it can shrink the jacket. Low - heat ironing is recommended if needed.
