Using this vintage O'Neill ski suit is easy. Just put it on like any other ski suit before you head out for a skiing adventure. When wearing it, make sure all the zippers are properly closed to keep you warm and protected. As for care, it's best to follow the washing instructions on the label. Usually, a gentle machine wash in cold water is recommended. Avoid using harsh detergents as they might damage the fabric. Hang it to dry instead of using a dryer to maintain its shape and quality. Store it in a cool, dry place when not in use to prevent any mold or mildew growth.
