I'm a long time skier, boarder and winter cyclist and use a downhill racing helmet for winter cycling myself. And IMO what you're looking at there has some issues. It might be great for keeping snow and wind off your face in powder conditions, but a winter biker works harder than a boarder and works up a sweat. Combine that with condensation from your breath and the inside of that helmet will get wet fast.

Yeah , I agree, a cold face is something I want to avoid myself, and what I find works best for winter biking is also what I'm using for skiing - a full face balaclava with a neoprene face mask built-in. Bring two and change when the first one gets wet. There are several on the market, here are a few photos.
