Price / performance = bomb

The helmet fits perfectly, sitting properly and has some little "extras" that I would not have expected in the price range. So is located at the bottom of the helmet is a setter mesh fabric, which provides a better fit to the neck, thereby reducing the penetration of cold air, while also allowing the damming of warm air further reduced inside.
Also used is a "nasal breathing device" available, which is designed to prevent the exhale through the nose, which fogs the visor.

That's the only point that in this helmet - still - is somewhat problematic. Despite the very mild Tempraturen outside the helmet with visor and open ventilation devices closed fogged (for closing 3 pieces, two permanently open) very quickly.
Since I use it on a scooter, it's a bit annoying when I can enjoy over 50 km / h "clear view" until speeds. I'm afraid that at onset of winter weather, this effect is even worse.

But fortunately there is this yes NanoProtect sprays / polishes, with which the fogging is to be significantly reduced.
Should anyone from experience have other, better tips, I am grateful and glad when one would give me this Share ;-)

Otherwise, I can only say that everything was great
