To use these ski pants, simply put them on like regular pants. They're great for skiing or other winter activities. When it comes to maintenance, you can machine - wash them on a gentle cycle with cold water. Avoid using bleach as it may damage the fabric. After washing, let them air dry. Also, make sure to check the zippers and buttons regularly to ensure they're in good working condition. If there are any small tears, you can easily repair them with a needle and thread. Have fun in your new ski pants!
