Just to give my 2 pence worth - I have always worn Arai Chaser helmets in a small, they fit tight at first, then bed-in, and moved to this exact same helmet in a small and a perfect fit from day one. It’s common that if Arai fits then x-lite will too. If you are Shoei or AGV then not likely a good fit. Genuinely the best helmet I have ever had and this scheme is amazing, shame it’s at a premium to get it. If I hadn’t got it then I would be buying!
Was really keen but I'm a medium - have just ordered via Infinity as Sportsbikeshop have no stock until 21/7. Have and AGV and Icon so am hoping this will be a good fit, despite comments to the contrary. Sorry for the hijack - GLWS.
