I am involved with enduro. I have helmets, and before settling on this one, I recently tried the AIROH twist 3 and AIROH wrap as well as the carbon ones from Raven. Three things I was looking for in a helmet are: - To be certified (meaning it provides safety) - To be able to put my goggles directly under the visor immediately when I'm not wearing them and to wear them directly when I need them (without straps or turning them behind the helmet) - TO HAVE VERY GOOD VENTILATION and EXHAUST. The helmet has all of the above, but what surprised me is the many ventilation and air entry points to the head. When I do enduro and take off the helmet, it's like I came out of the shower. With this particular helmet, I have very, very good ventilation and exhaust. It is not noisy and has a very good and large opening for goggles. I have tried it with 100% acuri 2, Raven strike, and Raven edge goggles, which are cinema. It's okay with all of them. The visor is flexible and theoretically doesn't break easily. I was between M and L. My head has a circumference of 58.5cm and is between M and L. The M was a bit tight at first on the cheeks, and I was worried, but I finally settled on it and didn't regret it because the cheek pads are very thick and have enough space to adapt to the cheeks. In the previous helmets I tried, the pads were thinner and squeezed me a lot, and in some impact, I assumed they wouldn't be enough to absorb the shock. (my opinion). I also researched the company. It is Chinese, but if you look it up, you'll see that it is one of the largest helmet manufacturers with a state-of-the-art factory. Watch videos on YouTube. Since I go out in the summer, I'm thinking of getting another one. I am very, very satisfied. If I hadn't tried this, the choice was one in terms of ventilation. The AIROH aviator 3, which also has good ventilation but still not like this one. This one is full of air vents. And the Aviator is 4 times higher in price. I say this for those who want good ventilation that they then have to go for a very expensive option. Don't be afraid of the pads that tighten the cheeks. When you wear it, see how compressed they are. If they have enough room, take it. Also, the mouthpiece of the bladder fits very easily into the mouth when you want to drink water or electrolytes. It has enough space between the mouth and the helmet. It doesn't cause trouble. Also, the chin of the helmet doesn't come out so much, and this facilitates head movement, providing a better field of view. I will return for an update
