I rock the outdoor technology yowie. By far the best thing ive tried. It doesnt freeze up and I can breathe perfectly fine. their website is Front page | OUTDOOR TECHNOLOGY
. Seriously check them out. Pretty cheap.
I'll +1 the yowie. Bought 2 of them last year and I love them. If you're a heavy mouth breather, like myself, I suggest you get 2 if you're going multiple days on a trip and chance of fireplace is slim.
I like that I can pull it up to my goggles and it stretches down into my shell. The half section of fleece is good over your face, but the lack of it towards the base keeps your neck warm but not too hot.
