Para-sport does have the right idea. But I do have to say that I ordered just the lens for my z1. When I first put it on my helmet it made my helmet, that was only 4 years old, look brand new. Down side was that the lenses had a magnifying effect to it. It seemed has if I had put on someones prescription glasses. Thought it was a one off so i did a reorder and had paragear look at the stock of lenses and they found the same thing. I had brought it to the attention of the company but the responds was a bit shocking. They said they knew about it but did not know how to stop that effect and were looking into it. Was told to just be looking more downward so i did not see that effect. Needless to say I took it off and sent both back, can not take the chance of not seeing correctly. The ground comes up quick enough do not need to have it magnified. :) When they can fix that issue I will be getting that shield for my helmet.
