Umbro shade cap. The photos are of mine, but I accidentally got two, so I'll send you the new, unused one. The shade is removable. It has an adjuster, so you can adjust the size. I think even those with larger heads can wear it without it being too tight. It's reportedly 62cm around the head. I couldn't buy it in Japan, so I got it from an online store in Korea. Please feel free to ask if you have any questions.
