When the wind chill drops into the single digits, it’s time to cover up the face!
A 16 mph wind is strong enough to hurt exposed skin at these temperatures.
After several experiments with various face coverings, I found these combo clava’s to do the job of letting me breathe while protecting against some pretty bitter weather. They are a lifesaver!
In these temps I can just put the hood up on my coat and wear a scarf around my neck for adequate comfort and protection. When the windchill drops into the negative double-digits I may need to add a hat over the clava.
