New to helmets but I'm also eyeing up Berns. At a local shop today, I tried on both large and XL of several brands. In all brands but Bern, large was a perfect fit. In the Bern's, I fit an XL. I guess they run a tad bit bigger.
I'm ordering online and getting an XL. Worst case scenerio, I can wear a slighly thicker head wrap if it's too big. Can't wear a helmet that's too small at all.
Rule of thumb with Berns: always go a size bigger than your typical helmet sizing. Kinda stinks, especially for people with large heads like me. I'm typically an XL.. but in Berns I'm likely a XXL and that even might be small :/
