Be careful, or your face will freeze like that.
I mean that literally. If you go out in the cold without a nice, warm outfit, your face is actually going to freeze. And most likely some other parts of your body will freeze too.
Thawing yourself out is an unpleasant proposition. It will be painful, to say the least, and possibly dangerous.
Avoid the problem altogether by keeping yourself warm with a North Face hoodie. Suitable for the arctic North, the antarctic South, and anywhere in between that happens to be just a little too chilly for comfort.
They won't necessarily cover your face, but they'll keep the rest of you warm enough that face-freezing is an unlikely possibility. A very unlikely possibility.
