Corduroy Driver Cap

When I was buying the hat on the website, I kept looking for different sizes, but there weren't any, it just says one size. So I bought it thinking that maybe there's some elasticity to it that could make it stretchable to any size, but when I finally received it, it says small on the inside! I was very confused to say the least! I have to return it because it's too small! So if you're thinking about buying this hat, just know that apparently it only comes in a size small! Other than that, it's a nice hat, the quality is very nice!
