Earlier today I bought the whisper strip kit for my Shoei helmet. It’s supposed to divert the wind and make it much more quiet in the helmet. To this point, I have been using earplugs when doing long tours, but now I hope that I don’t have to.

It looks like this when mounted on the helmet:

As you can see, it greatly reduces the size of the hole in the bottom of the helmet. The question is if it’s really enough. I will take a long trip tomorrow and really try it out, but I will bring my earplugs too, just in case.

Edit: Results of the test.
