The helmet is not worth the money.
Stay away!
Tragic whistling when the visor is open and it hits your forehead.
The air vent located in the mouth also makes a terrible noise.
The helmet is only quiet when the visor and air vents are closed.
Another big flaw, the visor did not sit properly on top and gradually fell off on its own.
Note that the helmet has not fallen off or caused any trouble to the mechanism.
In conclusion, Shark is tragic for selling a helmet for 550€ without it being well-designed and without testing it before production, because if they had, they would simply throw it in the trash.

Excellent visibility even with the internal sun visor, very stable at high speeds and completely silent with closed air vents. After long journeys and hours of use, it remains comfortable on the head.

Except for the small, non-annoying noise produced by the vents, the helmet is excellent as a value for money for someone who wants a carbon look. As for its interior materials, I would say that the quality is at a very good level. You can tell from the nice feeling it has when you wear it on your head.
