Using these ski pants is easy. Just put them on like regular pants before you head out for skiing. When wearing, make sure the pants fit well around your waist and legs for maximum comfort. As for care, avoid using harsh detergents as they may damage the fabric. It's best to wash them in cold water and let them air - dry. Store them in a cool, dry place when not in use to keep them in good condition. Also, check for any loose threads or damages before each use to ensure your safety on the slopes.
