Using this jacket is a breeze. Just zip it up and adjust the drawstring around the hood to your liking. You can wear it on its own during mild days or layer it over a sweater in colder weather. The pockets are great for holding small items like keys or your phone. When it comes to care, machine - wash it in cold water with like colors. Use a gentle cycle to avoid damaging the fabric. Don't bleach it as it may affect the color. Tumble dry on low heat and then reshape it while it's still damp. Always check the specific size chart for this item, as different suppliers may have different sizing. And remember, if you're used to US sizes, you might need to size up when choosing Asian sizes to get the best fit.
