Review on VOCALOL Protection Pollution Reusable Sports Headbands Sports & Fitness by Luis Esquivel

I have one of each color for my boyfriend and I, I use them for running and hiking in NH (so the mountains are tough). They all look as advertised as some sellers don't seem to give what is needed. It's better than nothing and quick enough to put on and take off, but man when you're gasping it's even harder to breathe and you're going to get sucked right into your mouth. At rest it's ok. I usually wear it around my neck so it tightens up quickly when I bump into people, when I'm 6ft it can be tricky so that 30 seconds to get past someone is fine but I'll pull it straight after that. The cord keeps it perfectly on my face, without it it will definitely fall.
