How to Use: Simply zip up the jacket when you go out in cold weather. It's easy to put on and take off. Attention: Check the size chart carefully before buying to ensure a proper fit. Since different suppliers may have different size standards, don't just rely on your usual size. Maintenance: You can machine wash this jacket on a gentle cycle. Use a mild detergent and avoid using bleach. After washing, hang it up to dry. This will help keep the jacket in good condition for a long time.
