I was worried about the quality of the product due to the other most recent reviews, but decided to run the risk on it as the price seemed fair for the amount, and I like the rounded shape over the "duckbill" K/N95 and these did have the best reviews for masks of that criteria. I survive Chronic Illness, including some immuno-compromising issues, so if you're looking to mitigate the burden of others' germs, read this review in full! These are KN95 masks, NOT N95. (Very important difference to note!) So YES, the fit is going to be a little looser on the face because they're not meant to be an airtight seal. But honestly, I really only felt it by my ears and under my chin. And even then, it still sat against my skin completely, but I could slide a finger under the edge if need be w/o it pulling. And there is plenty of room inside the main portion, so it is not pressing up against your nostrils or mouth either every time you talk/breathe. I honestly love the fit of these over the duckbill style, by FAR! As for the "thinness" a lot have mentioned, (again these are NOT N95 masks): I tested the ability to tear the material of the actual mask itself, and couldn't do it except for at the seams if I REALLY tried. I then cut it open to check if the layers were present as claimed by the listing, and everything is as advertised! The ear loops are comfortable and have a lot of stretch, and do so without tearing away unless you're intentionally doing so. They are soft and made of material similar to the lycra hairties that have no breaks/metal pieces, or fabric headbands. So they are comfortable to wear and don't pull on the back of my ears. The nose bridge is fine. In some masks the flexi-bit is slightly shorter than in others on occasion, but not so much that it interferes with the functionality. That's just the beauty of mass production, baby! As for my fellow corrective lenses homies, there is minimal fogging and this can be mitigated by just sliding your glasses a millimeter or two away from the edge of the mask rather than then being pushed all the way up against the edge of the mask/bridge of your nose. (They make really cute safety chains these days if you're worried about them falling off your face.) And lastly, the "chemical smell" is nothing beyond what to be expected. I didnt really notice a difference between other masks in the past and these on that front. They smell like sterile medical drapes, and you really don't notice it after a few minutes anyway. So, a far as KN95 masks go, I would definitely suggest these if you're looking to stock up on some, considering all present circumstances in mind.
