To use this jacket, simply put it on like any other outerwear. It's suitable for various outdoor activities like hiking or just walking around the city. When it's really hot and you're sweating a lot, unzip the underarm vents to let the air in. For care, it's best to machine - wash it in cold water on a gentle cycle. Avoid using bleach as it can damage the fabric. Hang it to dry instead of putting it in the dryer. Store it in a cool, dry place when not in use to keep it in good condition.
