Review on Ultimate Neck Gaiter: Multi-functional Headwear for Men and Women - Cycling, Fishing, Running, Hiking, Camping by Nick Henning

The product is a long elastic cuff that stays in place when you move your head - unlike a scarf or bandana which needs to be adjusted (you don't want to keep touching your face). The circumference of my head from the fleshy side to my nose (small bridge of the nose) is 19.5 inches. I put it around my neck, pull the back of my head up first, then to my ears and hold my nose. The material is thin but can be folded in half if needed. I've worn them to the grocery store and to my office where, by the way, my doctors return from ICU with +COVID patients but switch to medical masks when I know they're back in the office. I left it on as I walked through the office. I'm not sure if that's helpful, but that's what I'm doing right now.
