Yes, I bought it thinking that the chin piece would provide better protection against howling wind and sleet than a neoprene face mask. After using the RUROC I think it's mostly just a style thing. Again, I'll try it once more next season, but I'm not particularly hopeful.
If it doesn't seal out the elements then there is not much value there.
Crash protection would be the next question. The older I get the more paranoid I get. I have 4 kids snowboarding so I have a lot to be paranoid about. Do you think the chin guard would withstand an impact with a rail or tree?.
The better design would be a goggle and chin guard that pivoted up when necessary. If it worked like this motorcycle helmet that would be a big improvement. The goggle fog issue would not be solved though:
