I find that the 47 hats stretch pretty well if you soak the band and crown in water and then pull it down on your head. L are usually too tight and XL too loose, so I buy L and stretch them. Sometimes takes more than once, but I own a lot of size L hats from 47 (red with white front, black with red C, black with green C, brown with tan front, black with plaid front, etc), and most fit really well.
