I tried one the beginning of last year, or year before.
I got it because I will ride in stormy weather and needed better protection from the snow and wind than everything else I've tried.
It did block the snow, sleet, and wind.
But I only used the helmet a few times. Too heavy and I had problems with goggle fog. So I don't, and haven't used it since.
Besides, IF there's anyone out riding in conditions where the full face helmet is needed, they are miserable from what they have going on not working. See it all the time.
I tried about everything on the market and nothing performed to my liking.
So I made several different face shield / masks until I finally came up with something that wasn't heavy, worked good enough, and the parts I used are 1/4 of what the Ruroc costs.
Show some bizalls and put function over fashion!
