Thank you for viewing! This is a black hat with a nylon lining and a ribbon. It has a wire in the brim, so it should stay up and not flop down when you're working. The neck strap is adjustable and removable. The nylon lining likely provides some water resistance. Size: Approximately 57cm, adjustable with the inner ribbon. I bought this hat because I loved the cute shape, the adjustable ribbon inside, and the wired brim, but I decided it was too nice to use for work, so I haven't worn it. I'm selling it because I haven't used it. It's unused and in good condition, but I stored it with the intention of using it, so I've listed it as "Like New." I hope someone who understands that it's a pre-owned item will purchase it. - Color: Black - Design: Hat with ribbon
