Familiarity: I've used it several times
Wore this skiing in single digit temps and it kept my face and head at ideal temperature. Mouth/nose cover has perfect amount of tension to stay put but not too tight in multiple positions. Can be freely moved to cover both nose and mouth, only mouth, or under chin if you want neither covered and those adjustments could be made with gloves on. By the end of the day it was wet in front of my mouth, but still kept my face warm. Dried quick and not stinky.
