Size: Free Size Material: Neoprene. It's a material similar to a wetsuit. Color: Navy Blue Hello. This is a KENZO cap. I've only used it a few times since I bought it several years ago, so I don't think there are any noticeable scratches or stains, but there is a slight feeling of use. Also, please understand that it has been stored at home before purchasing. The color is listed as navy, but it may look black to some people, so please be aware of this beforehand. Thank you.
