Great hat, fits well.
I work outdoors in a sunny climate and recently resolved to wearing UPF hats rather than sunscreen. I hummed and hawed over a lot of hats, but as soon as I saw this it vaulted directly into the shopping basket. I'm 7 3/8" so was a bit nervous about the "Small Medium Large" nomenclature, but this passed the test of bicycling downhill into a head wind, a daily requirement, without any sign of looseness - yay. Oh, and it looks really sharp, sharper than the photo's I'd say? The right shaped hat for me (although your head may differ)!
