Got out on the bike after a couple of days trapped inside by heat and rain—still incredibly hot outside. I ordered a couple of these neck gaiters to use as face coverings while riding, and, while they are super thin (and maybe not super corona-effctive), they are still super hot while chuffing up a hill in 95-degree heat and 1,000% humidity. The gaiter form factor is nice because you can pull it up in people-dense areas and push it back down once you get back into the sticks. Gonna be a weird / sweaty summer.
