When I'm on top of Granite Chief at Squaw and the combination of wind and "snow" is trying to sand-blast me back to my youth, this is my formula:
* Turtle Fur neck gaiter
* Seirus Masque
I always thought the Masque was dorky, impractical and uncomfortable until I found conditions that were worse.
Personally, I'd never go for the hoodie. It flies in the face of my a-la-carte layering approach. My helmet's too tight for anything under it anyway. The neck gaiter is easy-on, easy-off and sometimes I wear it even when I don't have an insulating upper layer under my jacket.
