Speaking of tunnel hood, I know that the justification for fur trimming is that it will prevent moisture in the breath freezing on the face and injuring the skin. Will a faux-fur trim catch the moisture as well as a coyote fur? (Canada-Goose use coyote fur; Helly Hansen have both)
When the temperature was -25° C (-13° F) without windchill and with 35km/h wind during the day on december 20, I wore a cheap fleece balaclava from Misty Mountain that doesn't cover the mouth (I don't like to cover my mouth although it could be a good idea in some circumstances to protect the lungs.) and I'm surprised by its efficacy.
