These masks are comfortable to wear and are easily breathable. No weird smell. No scratchy surface on the face. The ear loops are stretchy and don't tug at my ears or interfere with my eyeglasses. I like the bendy part at the nose because other masks allow my glasses to fog up. These pinch tightly without being uncomfortable, so my breath does not escape and cause my glasses to fog up. If you wear glasses, I recommend these above other types.
