Great hat. This hooligan style hat not only makes me feel like a hooligan again, it also improves my ability to tell people how things used to be back in my day. The hat's old-timeyness is epic.

I got the large charcoal/red plaid. It looks exactly like the picture, and seems like good quality.

Large turned out to be the 7 1/2 (23 1/2 inches) for this particular hat. I know 7 1/2 can be considered large or extra large depending on where you are looking (it is large for Brixton and Land's End, but it is extra large for MLB.com and various other places).
