I like to wear the light blue pleated surgical masks. They are rather loose and somewhat comfortable, and since they don’t do diddly I can wear one for several weeks.

They do, however, nicely reduce your O2 intake with the added benefit of concentrating any viri and bacteria for your lungs enjoyment.
If you haven’t had the dreaded child-killing two day flu, then there are a host of other nice things you can receive by wearing a mask at any time, especially if it is used more that 4 hours and when washed helps the concentrations mount.
I wear a thermal gator that I also use for winter fishing. I have worn this where required for 2 years. It’s a lucky mask. Only got Covid once.
