This (black) Ecoguard mask only has one layer! If I had known, I would have picked the blue one, which - according to the description - has 3 layers, which is what I expected in this one too. But this mask only has a single polypropylene layer, which is too thin for my comfort. The customer service is excellent though, and I will purchase a different product next time.
No leakage or fogging of my eye glasses
The ear loops are a bit loose, but when you fold a small knot on each loop, it fits just fine. They are also good if you wear outside another mask, not tight. The mask has layers of protection, thicker than most surgical masks i have tried.
Ear loops on mask are too loose. Only 2 choices child or adult. The adult mask is loose on both myself and my husband.
I've only just begun using this mask, but find it very comfortable
