I tried on both Small and Medium, the Small fit perfectly. Unfortunately over time it shrank and now is too tight. So I ordered another. Same thing happened, so my next order will be a medium, with the spacers for a better fit.
The color faded on both near the sweatband so there is are irregular pinkish areas, probably from sweat absorption. I haven't tried cleaning it, though, and I haven't seen this happen on any of my other hats.
Other than that, I like it, looks good, and I need a couple of UPF50 hats. I especially like the ARPANSA rating - it bragged about it to my dermatologist.
