I submitted this same inquiry on another BMW forum and received very few replies so I thought I'd duplicate it here.
I am seriously looking at the HJC FS 10 helmet largely because of the built in sunshade. Short of prescription sunglasses it is nearly impossible to find non-polarized clip on sunglasses. Since the polarized glasses cause unusual light patterns from the face shield, I prefer to avoid them.
The real question I have concerns the noise level of the FS 10. Several reviewers have classified the helmet as noisy and that concerns me. Also, others have questioned the usability and location of the built in sun shade.
Does anyone have experience with this helmet? Are you satisfied with it or not? Do you think it is noisy compared to other full face helmets?
