This thing is HUGE!  It is difficult to wear it in a non-full face cover arrangement.  It is not really suitable for use other than completely covering your face.  It will also BAKE you if it is not VERY VERY cold out.  If you live on the north pole this is the face mask for you!!

Good:  VERY WARM.  VERY LONG, covers your chin easily.  Can be used with a scarf to protect chin/neck completely. You want this hat during a snowpocalypse or invasion of ice monsters. Or if you work outside in the cold winter, this is your hat for sure!!

Bad:  If it isn't VERY cold out you are going to BAKE wearing this thing.  It is not practical to roll it up and use it like a "normal" sock hat, doing so doubles the thermal protection, the top of your head will be 220 degrees in just a few minutes.  Rolled up like that, it also looks like a freaky large blanket wrapped around your noggin.
