I am a small large and a big medium in most anything I can wear. I bought the Large flake and it fits just fine and was happy with it. Over time the ear padding gets a little softer and now i notice some wind noise. I tried my buddies medium and it fits better I think, so I bought a black gloss as a build finish reward. I will wear either one, both are not uncomfortable. You can see some bulbous difference between the 2 sizes but its barely noticeable, especially when my jacket has armour in it anyways and makes me look bigger. They fit true to the size chart, but like I said, I am between 7 1/4 - 7 3/8 new era hat size so either one fits. Great quality helmets.
I got one from thebellstore I think, and one from extremesupply, both online to Canada, both under 140 after shipping.
