A balaclava (military grade) might be a good choice. You can get some ones that look rather thick, but are breathable. They'ed have a number of different colors, whith the exception of yellows and reds, but the sand or tan could be used as a "Sand gold". I don't know if you mention the color or if i missed it lol. They are sturdy and would look the part, you probably wouldn't need to add the top piece to the mask then.
