I love these goggles for the fact that they offer superior vision (compared to my oakley crowbars) and the lens offers great visibility in low light.
I hate the lens because it scratches so easily!!! I know its inevitable but these scratch super easy. very difficult to clean on the trail as well because the lens is so fragile.
If you can take care of your lens have have a POC helmet these are amazing. Don't get me wrong I still wear them with a scratched lens because they are amazing. I would highly recommend these goggles, I'm just warning you now, plan on the lenses getting scuffed.
