I never tried those, but they sound better than a plain ole hood to me. Do they limit your vision?
I mean hell, if you like it, and it is comfortable and keeps your head warm (which is where you lose the majority of your body heat), I say rock it. Shit in 10F you may need a full face mask anyway if you don't like the cold or have some gnarly facial hair for insulation.
Wow really? Even if they are the tight ninja mask style?
