Yeah, the one I had that worked relatively well, the piece was like a headband that went over your nose/mouth.
Problem is, that covers a narrow range of maybe 5-15f. Once you get to 5-10f you get into the range where any exposed skin is vulnerable to frostbite. Keep in mind you're riding into the wind of course. So having something that might leave some skin exposed is...iffy.
I don't recall the exact temps any more, just because like I said I realized it wasn't a lot of fun riding below 15f so I stopped doing it. Others who ride in those temps regularly for transporation might have better experience than I do.
