If anything, I'd have been tempted to make the black patch and crest much bigger.

I'm normally a large and bought a large which fits fine. I think there's a fair bit of exaggeration going on to be honest, seem to remember people complaining about the sizing most years

I'm inclined to agree with that and am going to take a gamble and order a large myself as always. Why change the habbit of a lifetime and all that!

Wad going to order one now, but no mediums listed.
