Just wondering and if anyone has a ridiculous amount, though I can see at least 11 being 'justifiable'. Maybe: XC lid, a more bulky XC half face, a DJ/MX/skate helmet, a road helmet, a full face helmet, a helmet to commute and a helmet each to race XC, CX, road, DH, BMX ..
I use one for all my bike riding at the moment (an MTB half face). I used to have another to commute but its a bit small and I no longer commute
