About gaiter
Gaiters are garments worn over the shoe and lower pants leg, and used primarily as personal protective equipment; similar garments used primarily for display are spats.
Originally, gaiters were made of leather or canvas. Today, gaiters for walking are commonly made of plasticized synthetic cloth such as polyester. Gaiters for use on horseback continue to be made of leather.

About COVID-19
Coronavirus disease 2019 (COVID‑19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It was first identified in December 2019 in Wuhan, Hubei, China, and has resulted in an ongoing pandemic. The first confirmed case has been traced back to 17 November 2019 in Hubei. As of 10 August 2020, more than 20.1 million cases have been reported across 188 countries and territories, resulting in more than 737,000 deaths. More than 12.3 million people have recovered.Common symptoms include fever, cough, fatigue, shortness of breath, and loss of smell and taste. While the majority of cases result in mild symptoms, some progress to acute respiratory distress syndrome (ARDS) possibly precipitated by cytokine storm, multi-organ failure, septic shock, and blood clots. The time from exposure to onset of symptoms is typically around five days, but may range from two to fourteen days.The virus is primarily spread between people in close proximity, most often via small droplets produced by coughing, sneezing, and talking. The droplets usually fall to the ground or onto surfaces rather than travelling through air over long distances. However, the transmission may also occur through smaller droplets that are able to stay suspended in the air for longer periods of time in enclosed spaces, as typical for airborne diseases. Less commonly, people may become infected by touching a contaminated surface and then touching their face. It is most contagious during the first three days after the onset of symptoms, although spread is possible before symptoms appear, and from people who do not show symptoms. The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors; however, guidelines do not recommend using CT imaging for routine screening.Recommended measures to prevent infection include frequent hand washing, maintaining physical distance from others (especially from those with symptoms), quarantine (especially for those with symptoms), covering coughs, and keeping unwashed hands away from the face. The use of cloth face coverings such as a scarf or a bandana has been recommended by health officials in public settings to minimise the risk of transmissions, with some authorities requiring their use. Health officials also stated that medical-grade face masks, such as N95 masks, should be used only by healthcare workers, first responders, and those who directly care for infected individuals.There are only one registered vaccine so far – Russian Gam-COVID-Vac – but there are still no specific antiviral treatments for COVID-19. Management involves the treatment of symptoms, supportive care, isolation, and experimental measures. The World Health Organization (WHO) declared the COVID‑19 outbreak a public health emergency of international concern (PHEIC) on 30 January 2020 and a pandemic on 11 March 2020. Local transmission of the disease has occurred in most countries across all six WHO regions.

Before there was COVID-19 there was sunburn and skin cancer, elevating the use of neck/face gaiters to provide UPF protection. For sailors, rather than repeatedly apply sunscreen, the gaiter was a continuous shield to protect the face and neck from harmful UV rays.

So when COVID-19 became a thing, and masks were required to limit the spread, the convenience of the gaiter made it an obvious choice for the task. But how well does it work? Maybe not too well according to this report:

The U.S. hit another grim milestone on August 10 with more than 5 million Americans now infected with the coronavirus. Although there is a push to increase testing and develop a vaccine, experts continue to suggest that if all Americans wore masks, the pandemic could be brought under control “within weeks.” In the spirit of that mission, a new study published in Science Advances is shedding light on which masks are most effective — and which may actually be hurting the effort to curb COVID-19.

The analysis, carried out by researchers at Duke University School of Medicine, relied on an “optimal measurement method” that uses a laser beam and cellphone camera to track the number of droplets that emerged from an individual while he or she wore a mask. Of the 14 masks, the two that proved least effective were a bandanna and what the researchers refer to as a neck fleece, also known as a neck gaiter.

The most secure mask, an N95, led to a droplet transmission of below 0.1 percent. But handmade cotton and polypropylene masks, some of which were made from apron material, also proved effective, with droplet transmission ranging from 0.1 percent to 0.4 percent. One mask, which was knitted, released a higher number of droplets, from 0.1 percent to 0.6 percent. But none of the masks compared with the neck fleece, which had 110 percent droplet transmission (10 percent higher than not wearing a mask). Full report.
