We bought two brands masks from Kollecte due to great reviews and testing results we saw online and we have a various assortment of maks, like everyone during covid, that we purchased locally or online. This mask had the highest reviews, followed very closely by the original "Evergreen Cleantop mask" (not the Evergreen Cleantop 3D version) and I can see why. Comparing to 2, the BOTN material is slightly thicker & stiffer so its less likely to collapse and its adjustable ear loops are easier to adjust but we had one issue with the BOTN. Its too big vertically.
The cleartop is 5.9" versus the BOTN's 6". It doesn't seem like much but for all of us, even my husband and son, who have bigger faces, it was up to the top of our cheekbones, making it very uncomfortable with glasses. And in my face (smaller woman's face), it additionally was poking into my neck below. :( The evergreen cleantop was a much better fit.
