Thye provide them.

I don't wear a face mask as I'm exempt due to a respiratory condition... but I do wear a face sheild as I figure it's better than nothing... i try to wear it outside but it's tricky in current weather conditions... For example when I was walking to my office today it blew off my head and nearly rolled into the road....I nearly face planted trying to catch it and then spent 10 minutes anti bac' ing it so i could wear it until i could get to my car to get a replacement...

You could wear a scarf. That will also protect you from the cold.

I wear one in the supermarket but nowhere else. Not that I go anywhere else right now.
