This is an excellent hat. It fits perfectly. Because it's a fitted hat, there's no one-size-fits-all opening in the back. It fits perfectly, with just the right amount of stretch so that it stays on my head but isn't too tight.A slight downside is there's not quite enough ventilation at the top of the hat, with four measly holes. But if you want mesh, you're getting into trucker-hat territory, which I don't want.I like the low profile of this hat, and its soft fabric makes it comfortable for wearing on long walks, especially on cool days. I like it so much I ordered another one in the khaki color. Highly recommended!
