I purchased several masks both on Gearbest and Amazon, and this is by far the most comfortable and breathable. I can adjust the elastic around my ears. These are the only masks that my husband will wear. The other masks pulled on his ears and were uncomfortable to wear for extended periods of time. Thank you for a well-designed mask!
So the problem I have with masks is they are too big for my face. This mask was a great fit. There is a clip for the nose so you can get a snug fit there. Material is thick but comfortable. The mask goes under my chin so it’s snug all around my face. The mask goes a little close to my eyes, but it's firm enough so it doesn’t steam up my glasses.
These work perfectly and fit comfortably. They don't crush your nose or fog your glasses like regular cloth masks. You can breathe in it without any material of the mask being sucked in. They are easy to put together, if you have trouble make sure the lining isn't upside down? I would purchase more for my family members.
