Good cotton and adjustable earloops make these an ok basic for toddler to early elementary
So far with my kids, I have kept them out of air conditioned areas, and just had them wearing jersey knit 100% cotton face masks that aren't particularly tailored.  With school being in person or bust this coming year, I am getting additional face masks so that I will always have enough as the kids loose them.  This one seems good for young kids maybe toddler to early elementary.  It seems to be all cotton as described, and the fabric seems good enough.  It doesn't have nose wire, which is the only flaw (assuming you get the fit right for your child's age).<br /><br />Size:  I have 4 kids, ages 1, 3, 5, and 7.  These masks are a perfect fit for the 3 year old, and also fit the 5 year old.  The 5 year old seems to have a small face.  These are a bit small for the 7 year old.  He is almost 8.  They work for him, but for that age I would go a little scootch bigger.  For immediate use for a 7 year old, they are OK, but I'm kind of assuming things will last long enough for masks to be outgrown.  The 1 year old pretty much takes anything off, including regular clothes, but these masks seem like they would be a good for for her.<br /><br />Material and filtering:  These are 3 layers of cotton - 2 of good quilting cotton and 1 of a more open weave.  The outside pattern is two pieces of patterned quilting cotton put back to back and sewn together.  Then inside there is a layer of white cotton fabric that makes a pocket to where you can slide a disposable filter between the colored front pieces and the white inner piece.  The 5 pack of masks came with some disposable filters.  I feel that the cotton is good enough quality to work well as a filter.  I had read about filtering and 100% cotton in a quilting weight does pretty well as a filter.  The 2 layers of quilting cotton that make the colored front part of the mask seem good.<br /><br />Fit:  These do not have any wire in the nose.  I have found that for me, a gap at the bridge of my nose is the biggest issue with mask fit.  For kids, I see more masks that aren't particularly tailored, and something is better than nothing, but a nose wire would allow for a better fit to keep air from going around the edges of the mask.  Other than that they are good.  The ear loops are adjustable with a silicone bead that slides to make them tighter or looser.  I tied a knot in each earloop on the outside past the silicone bead, to make it so my kids can't pull the beads off.  Even with the knot, there was enough loop to be able to adjust and get a good fit on each.<br /><br />Style:  The stars is a good gender neutral option, where it has some pattern so you can recognize it and kids can know which mask is theirs.  Meanwhile, the boys are fine with it and the girl is fine with it.  The boys are at an age where they are whiny about not wearing girl stuff.  Girl wants to be super girly, but says she likes these OK, I guess because it's a neutral.  Anyway, the stars are a pattern but it's so tame that it's basically just a pattern for kids to see and recognize their mask, but seemingly not enough of a pattern to offend any of them.  That seems good for kids.  I got the "Multi #4" pack.  In person, the red is a little more vivid, and the other colors look about the same compared to the online pics.  The overall color tone is fairly neutral with even the green being dark enough to be neutral with the red as the only real color in the pack.<br /><br />Problems:  There is no nose wire.  So there almost certainly will be a gap around the nose where air will go around the mask rather than through it.  The silicone beads can be pulled off.  Kids will pull them off.  Like I said, I tied a knot in each earloop out past the silicone bead and that keeps the beads on.  When I did that, there was still enough earloop to get a comfortable fit for the kids.  I put the knot out at the edge, so when you tie the knot make it out as far as you can so you don't use up the loop.  If your kids do pull the bead off, you can take dental floss, thread it through the ear loop, then put both ends of the dental floss through the silicone bead and use it to pull the earloop back through the bead.  So, it's a fixable problem, but fix it right when you get these and before your kids pull the beads off and loose them.<br /><br />Overall, these are an OK basic mask for kids.  These masks fit the toddler to young elementary age, but I think for older elementary, maybe these are a little small.  Masks seem to be 100% cotton and just a bit tailored.  That's a positive.  The only flaw is that it doesn't have nose wire, so some air will leak at the nose.  Compared to bulk packs of stretchy fabric masks from relatives, Costco, and Amazon, these are toward the high end for quality.  That's because sometimes the internet says "100% cotton" but it's really polyester.  These masks are what they say there are, and 5 masks in a pack is enough to have some spares.  If you find masks elsewhere with nose wire and good material, then go for the nose wire for a better fit.
