    Great fit

    Love the hat. So light, breathable, and comfortable. Love the curve of the brim. Thanks for a new hat that I can wear everyday.

    It’s pretty good. The logo is solid. The minimum size is almost too big for me. The front of the hat sticks up more than I would expect, making the back seem to be a sudden drop off.
