MITSU-Q Men's Knit Cap, Extra Big Size Knit Cap, Large Size 3XL, Black Although it's for men, women are also welcome to purchase. It's a washable knit cap. I bought it because I wanted a large size, but it was bigger than I expected, so it's almost new, only tried on. It's quite large. I don't think you'll find a big size like this from other manufacturers. Please check the size in the photos and images before purchasing. Thank you for your consideration.
