I've used Nolan flip-ups for 25-years. They are not Snell-certified because Snell don't have a flip-up standard. Mine is imported from Italy and has all Euro and Canadian certification—but not even DOT. I just never could stand pulling off my Shoei and ripping the glasses from my face by mistake. I started with BMW system helmets (made by Schuberth) but they became outrageously expensive after my second one. One caution is they run small so best to find somewhere you can actually try them on. They do not sell the version that I have (N100-5 Plus) in the USA, but the non-Plus is here. I wear a Bell 7-5/8, an extra-large in a Shoei, but a XXL in the Nolan. Years ago I had to import a case (12) of them just to get my XXL which no one in the USA carried. Sold the extras instantaneously, most of them to the local BMW dealer.
