Excellent fit and quality of materials as well as stability. It offers very good ventilation (perhaps the best), aerodynamics, and visibility. Very nice feel when wearing on the head both for its stability and the feeling provided by the cushions. Worth its money

I have purchased the frost black and I use it in the city. I have had the helmet for a year now and I decided to write a review because during this time it has suffered a lot of damage without much use. I am giving it only 2 stars because a helmet of this caliber should not get marked so easily and have its parts break so easily as well. The first marks appeared 10 days after the purchase when it was in a suitcase tied with the suitcase strap, after a short trip. Overall, it gets marked very easily and the spoiler broke in less than a year. The replacement costs around 50€. I expected much more because I come from a much cheaper and lower quality helmet (a Nolan worth 250€) which I had for 7 years and externally it had no damage, even though I used it exactly the same as the Arai. Although it fits very nicely and is not particularly heavy, I would not buy it again because with this amount of money, the color should not fade so easily and the external parts should not break so easily.

This helmet is not lightweight, it is 1600 gr+. However, its weight is perfectly distributed and balanced on the head. I use it on/off the bike. The noise from the air turbulence is less than any other helmet I have worn, really minimal. Without the helmet, you can hear the exhaust 10/10, but with the Quantic, it sounds like 4-5/10. Its aerodynamics are noticeable, especially at speeds of 150+ km/h, you feel like the helmet is gliding through the air.
The ventilation is excellent, and you can choose how many vents to open. It feels like it embraces the head harmoniously without excessive pressure on the cheeks, ears, and top of the head. Truly excellent. Arai equals guarantee!

Very good helmet. If Shoei helmets fit you, then this one is very close in shape. The difference I noticed is that it feels like it embraces the whole head, not just the cheeks and forehead like most helmets do. As a small negative point, I would mention the visibility, but I might be wrong because before I had a Shoei Glamster with a very large visor. Also, compared to the old one, it has very little noise and better aerodynamics.
