The outer shell of the N100.5 is made of Lexan, a special type of polycarbonate that is stronger and more durable than the polycarbonate made for almost all helmets. The visor is even large and wider, so you have a wide vision, almost like wearing a jet helmet. The ingenious hinge system of the chin can be tilted at two points, so that it is in the open position just above the helmet. This increases the aerodynamic and you can drive 'open' with relatively low resistance.
The Nolan N100.5 has a double homologation (P/J inspection). This means that this helmet is approved as a jet helmet and as a full-face helmet. So you can ride with the chin without any consequences. And let this helmet be perfectly suited for this. The chin has the safer opening mechanism 'Dual Action'. To open your chin, you need your thumb and forefinger. You can still open the helmet with one hand, but thanks to this extra protection the chin will open much less quickly in the event of an accident.
