This functioned very well but when skiing in very cold conditions with a helmet and goggles it irritates the bridge of the nose.  Just too much bulk of material in that area.  Cushion material is provided but really just adds more bulk and pressure.  Maybe they could lower that section to accommodate ski goggles on the bridge of the nose or replace that section with neoprene.  Also, you will get a lot of condensation in the cup that drips out on your front.  It still keeps that frozen condensation away from you mouth and gives you an air gap to talk.  Bottom line,  I like it but I can only wear it one day because the next day my nose is too sore/irritated.
