I'm always hesitant about ordering clothing on-line.  But I already have many FlexFit hats and they always are L/XL.  This was totally perfect.  And the hat is much higher quality than I expected!  It fits well, is normal for the size, and the quality is higher than expected.  EXCELLENT !!!

Its a great hat, but shipping was a really bad experience.  I would try and make sure fulfillment is by Amazon.  I have ordered at least 6 of these hats over the years.  I am taking away one star because they do fade after about 3 months in the sun.
