Perfect isolation from the air on the head and hands. Fuel consumption increases by about half a liter and finally, it needs some work during installation to avoid creaking.

It saved me from air fatigue, mosquitoes, and noise

For the winter, it is very good, you don't feel anything. In the spring, I use the factory one because I do long trips and with the GIVI, it reduces power and increases fuel consumption. If you install it correctly and put some foam material in between the black plastic, it doesn't make any noise.

First of all, it does not have proper application compared to the original and it creaks when in contact with the plastic cover. Others who have the same one told me the same thing. It creaks for everyone, but one person wrote it here so that others wouldn't fall for it. However, the most important thing is that after 2 months of having it on, it developed 4 internal cracks that you couldn't even feel with your finger because they were inside the material! I went to the merchant where I bought it and the guy tells me to send photos to the representative. He sends the photos and we wait. After a month, I go there and he tells me that they didn't respond. He sends the photos again and even after 2 months, still nothing. In short, there is no warranty. Tragic. So I wasted 140€.
