Anti Pollution Face Mask with Military Grade Protection | Anti Smoke, Exhaust Gas, Dust, Pollen, Allergens | Hiking, Running, Walking, Cycling, Ski and other Outdoor Activities (Medium, Black)

Great product but the back strap is too small. Keeps falling off when I turn my head. They need to make larger sizes. I do not have a big head so I don’t why they make the back strap so small. If it is too large you can cut it if you want. If it is too small there is not much you can do.

No sirve, no se detiene a menos que lo sostengas con una cola de caballo.

No es buen producto. Es un timo.

These newer versions of this mask are a lot better than the older version The Devil's in the details as they say there's a trip that comes with the filter that is for you where you push in where the nose is at it even has it in the diagram so it doesn't fog up your glasses if you use that it works very well and it will not fog up your glasses this have to make sure that the filters in the correct way and you can also use that by the picture in the diagram on this product.

I tried to really love this mask, but unfortunately the strong chemical smell is still there after months of airing it out and off-gassing. When I purchased it, I wasn't aware of what material it was made of (neoprene) or I would have passed on this one. Anyone else with chemical or toxic smell sensitivity should not get this mask. I aired it out for months hoping the odor would go away, but it STILL has a strong odor a year later and I cannot tolerate trying to wear it. I don't want to be inhaling those fumes either. It was a bit large for my face (female), but it seems to be well made and I like the design. I missed the window for return or I would have. I bought the extra insert filters too. I purchased a different simple all cotton mask that does the job for me, and without any toxic smell.
