This is a cap from H.W.DOG. It's very warm. Size is 40. As someone with a large head, this size was perfect for me. I think it's essential for winter as it can warm your ears. I'm selling it because I don't have many opportunities to wear it. I think it looks stylish when worn a little casually. I think it will be useful for winter activities such as going to the park with children, during snow sports, and other winter activities. Thank you.
