Face Mask with Breathing-Valve 5 Pack | Breathable Grey Face Mask for Women and Men Anti-irritant | Sports Face Masks Lightweight & Comfortable on Skin

Me parecio un producto tal como lo efrecen muy util Gracias

These masks are very comfortable to wear, and I can wear it through a complete cardio workout (no problem breathing through it). I feel safer with it on since it is KN95. It fits me and it fits my bigger headed husband (very versatile in fit).

I purchased these to go with my battery powered positive air pressure mask. I used a 1/2" grommet kit to punch a hole in this mask for grommet fitting to air supply tube. Now i have a rigidish type mask with a valve and fresh HEPA air supply and simply love these masks. They are above average by themselves compared to standard face coverings. If your getting fustrated with regular masks give these a try, for the price they are very good.

I found the ear straps to be attached very securely. The way this is curved at the nose to chin, it doesn't allow air to fog up my glasses which is great. Comfortable and easy to use. Quite roomy at the nose and mouth, and very comfortable fit with no gaps. It's breathable, even on long grocery trips and errands. I am more of a mouth breather, so after a point I usually start to feel a bit of heat and dampness. My wife thought it would be too small at first, but after putting it on, I realized that the fit was so good, it didn't matter. All in all, I felt very protected and found that the constant adjustment that I experienced with other masks was not required.

esta mascarilla es la peor inversión que he realizado, son muy pero muy fina, no tienen un cierre hermético y no se ajusta a la cara, no recomiendo a nadie comprar este producto, no gasten su dinero, en las fotos se ven bien, pero en físico , todo lo contrario.
