This is a gray sauna hat with the Spa Alps logo embroidered on it. I bought it as a souvenir about four years ago when I visited the place, but I haven't had a chance to use it, so I'm selling it. It has been stored at home and has never been taken out of the bag. It's the initial cloth version, not the newer mesh version, and the serial number is 520. If anyone is interested, I'd be happy to sell it. Thank you.
