Duke University tested masks using lasers. The wanted to see how much came through various kinds of masks. Neck gaiters are so porous that, as the person exhales through it, the fabric breaks up the larger particles into smaller one which will hang around longer They say that if you can see light coming through your mask, or if you can easily blow through it, it's not doing its job.
Unfortunately, the purpose of a mask is to protect the public from the wearer, so if people insist on wearing gaiters or pulling their T-shirt up over their noses, the virus will continue to spread faster, as it has been doing lately.

I think that what the "neck gaiter" was made of would have an impact on its efficacy.
Polar fleece I would expect to be more effective than say the typical material a T shirt is made of.

I agree, seems pretty basic but people tend to miss the concept.
But, the probable cause of spread would appear to be the social interactions at close distances as practiced at in bars, at parties etc. Its tough to be understood in a crowded bar with a mask on so I breathe thru my fingers instead of a mask. Sorry, that was just a wild sarcastic remark that came to mind, to remind certain offenders that their cooperation might help.

The news reported studies have shown that fleece is bad - it also breaks up the virus into smaller particles... They recommend 3 layers of tight weave cotton.

The mantra now is
1. sanitizing hands
2. social distance
3. mask
4. avoid crowds, which includes most bars

CNN online has an article about Duke researchers who did a comparison of 14 types of mask.
"
The most effective mask was the fitted N95. Three-layer surgical masks and cotton masks, which many people have been making at home, also performed well."
"
Neck fleeces, also called gaiter masks and often used by runners, were the least effective. In fact, wearing a fleece mask resulted in a higher number of respiratory droplets because the material seemed to break down larger droplets into smaller particles that are more easily carried away with air.
Folded bandanas and knitted masks also performed poorly and did not offer much protection.
'We were extremely surprised to find that the number of particles measured with the fleece actually exceeded the number of particles measured without wearing any mask,' Fischer said. We want to emphasize that we really encourage people to wear masks, but we want them to wear masks that actually work.' "

Here in McAllen TX they have shut down restaurants after ten pm. It seems they magically turn into nightclubs. Masks and social distancing and everything else to do with staying safe is out the window. It doesn't count here because we are having a good time.

Good times tonight at a bar or nightclub may result in many admissions to the hospital in another few weeks, and that is what is important to them right now.

It only makes sense that stretching a single layer fabric, for example stretching a neck wrap from around the neck upwards to make it also cover the mouth and nose, would increase the gaps between fibers in the fabric, opening larger portals for exhaled droplets to pass, with the potential to split droplets into a finer mist that might suspend longer. To be effective, cloth masks must consist of at least two layers, preferably of different fabrics.

Modern day "Russian roulette" or perhaps auditioning for the 2020 Darwin Awards.

Yes, and I wish more folks practiced it.

Yes, I realize they feel invulnerable to the disease, with minimal effects if they do get it. I hope, however, that they remember to apologize to their parents and grand parents who they pass it along to.
