I bought this hat because I live in Florida and needed a hat that provided more sun protection than a baseball cap. I have several very straw hats that I use for gardening and fishing but they are a little too big and noticeable to wear in public outside of those activities. This hat fits the bill perfectly. It's not nearly as dorky looking as my fishing and gardening hats but still provides a lot of sun protection. It's somewhat dressy looking, lightweight and holds it shape.  I have a fairly large head but bought the small/medium size so as to have a tighter fit. I tried the large/x-large size on in the store and it felt comfortable but sat somewhat loose on my head. I plan on wearing this hat to the beach and in other potentially windy situations so I didn't want to have to worry about it blowing off my head. I like this hat so much that I might buy another one to muck up while fishing and gardening.
