This is a universal master level. A neck gaiter of an extra elastic polyester fiber will work for you anytime, anywhere. You're always on alert, and you won't be surprised by the rapid change in weather or the alien gas attack. Over the mouth, over the nose, over the face, over the head... Whatever you want, let's go at them!
Very pleasant elastic fabric with great breathability, of course in fancy designs. Look at the photos and get inspired.
