The only slight downside is the condensation created which after a while in the freezer dribbles down the outside of the mask and freezes making a icicle slobber trail

I did put a few small stitches from inside to outside in the mask to pinch the neoprene together a bit around where it is cutout to show the filter type material

They either press my nose in or fog my glasses

The heat exchanger warmed and humidified the air so my lungs never felt like they were getting blasted with cold air the weather advisory on the radio was warning people to not breath deeply and to minimize talking if they had to be outside today
