To use this jacket, simply zip it up and you're ready to go out and face the autumn chill. When choosing a size, make sure to refer to the size chart carefully as each item may vary. For daily use, you can keep your small items like keys and phone in the three exterior pockets. When it comes to maintenance, avoid machine - washing this jacket as it could damage the leather and suede. Instead, gently wipe it with a damp cloth for regular cleaning. If there are stubborn stains, it's best to take it to a professional cleaner. Store the jacket in a cool, dry place when not in use, and avoid hanging it on a sharp hanger to prevent any damage to the fabric.
