Review on 🎃 ARRUSA Halloween Face Cover: Stylish Neck Gaite Bandana Scarf for Motorcycle Decorations and Outdoor Sports - Men & Women by Ryan Fitch

So this is light and a single layer. The ear loops don't really stay up very well when running, especially once you start to sweat. I trail run and you can usually stay 6 feet away from others on the trail, but because of the pandemic I got this for those rare times when I couldn't. It's only a single layer, so I wouldn't use it indoors! But for a brief encounter on a single-track trail when you have to quickly pass someone, it will do. The trails I run are pretty empty, so I don't need to try to keep it up all the time. I don't think it would stay if I did, especially once It's picked up some sweat (nor is it breathable once you start to sweat). Light enough to wear in warm temperatures though. It does what I needed it to do, regardless, minimizing up my exhaled breath for brief trail encounters. No idea how much sun protection it provides, but more than nothing, certainly. Just don't expect to keep it up over your nose and mouth continually if you are exercising hard.
