This helmet does everything it advertises. The fit is perfect. I wear glasses and the shade works well enough that I don't have to change to sunglasses. The vents work very well and its not to noisy. The pin lock ant-fog visor is amazing, I was surprised to see how well it work. Absolutely zero fog.
If your head shape is long oval this fits the bill better than most others. Its a good idea to measure your head shape with some calipers or something like that, you can make them out of cardboard or wood. The tip off to needing this helmet shape is that your forehead is squashed and branded by the pressure of an ill fitting too round helmet. This helmet also seems to have better airflow than previous Arai's I have had, I can feel a cool breeze across my barren scalp. Otherwise top shelf all around for materials, fit and finish.
I am very pleased with this helmet! I have used on the trails and roadways in Yosemite and the helmet did great. Helmet fit according to spec. Even on the freeway the helmet does well with air and noise.
Can't argue with ArI protection.
Good fit, looks good, excellent protection.
No issues with rattling peak, but then again I am riding a dual-purpose/enduro. Speed is not an issue. If you're going over 80, don't ride with enduro/off-road helmet.
The reviewer that complained about the cheek area being too tight clearly has not read the manual - this helmet has peel-away layers within the interior to custom fit your head. This is a great helmet with the single exception of wind whistling. No matter what configuration I use for the vents, I am assaulted by whistling that is clear despite using ear plugs. A minor gripe, but an honest review of an otherwise outstanding lid.
