Many are questioning whether their neck gaiter is ok to wear as a face covering.
A recent Duke study which suggested that gaiters are not a good face covering, was not an all-encompassing study. It was actually meant to test for an effective way to test face coverings, not to test the face coverings themselves. This could explain why the specs for each mask tested are unclear. I found several articles which suggest that the notion that neck gaiters are bad is not helpful. It is unlikely that any covering would multiply droplets, and any publicity that steers the public away from wearing a face covering is not good for the overall message, which is that any face covering is better than no face covering. Here is a New York Times article which points to another, gaiter-specific study.
It’s unclear the exact specs of the gaiter that was tested in the Duke study, except that it was a thin neck fleece. A most affordable product that I know well is 100% Micro-fiber 130gsm, so I decided to compare another gaiter with that item. I don’t have lasers or a controlled environment, but I do have a pretty large iced tea dispenser that could simulate an adult sized head. I also have a camera in my phone and a flashlight. So I stretched both over the iced-tea-dispenser-head and took some photos with and without the flashlight inside the “head” to see if we could see a difference in the porousness of each item.
