Do snowboarders wear bandanas?

i've seen a few snowboard videos and it appears that the boarders are wearing bandanas, unless i'm mistaken.
Are they wearing bandanas or some other sort of face mask?

I can't speak for all of them, but Shaun White (olympic gold medalist in two different winter Olympics) does. As a ski mask, too.
