When hats are sized S, M, L, XL we are always in amateur hour. Hats are sized properly metric by centimeter, or the old 7 1/4, 7 3/8, etc. Sure enough, this size Large hat is loose on my 7 3/8 head. Fur felt usually shrinks to fit, though, so hard use--sun, wind, rain, etc., will conform it eventually. Foam pads in the band? Also amateur hour. I suppose it's a fair point to say that cloth sweatbands are amateur hour, but that was the feature I wanted for hot weather/strenuous activity such as hiking or dancing.
