Love the Look Studios sent me some updated fabric covers for 3M Aura N95 respirators.
The updated pattern worked very well for me when I tested it out at a wedding, covering the mask extremely well and staying out of my eyes. I wore it over a 3M 9210 which has white braided elastic straps.
The 3M Aura is a very breathable mask to begin with, and not much affected by the cloth cover. There is still a little bit of exhaled air that is redirected back towards my eyes from under the cover rather than going through the cover fabric. So, the 3M Aura is still a bit more comfortable to wear without the cover, but I'm willing to take the trade off for special occasions.
I have tested the earlier, almost identical, design with a PortaCount mask fit testing machine and a pressure meter.
In my case, the fabric covered did not affect fit or filtration much and I still passed a fit test. Breathability was reduced a little bit, by about 12% or so. So there is a trade-off. However, many n95s are much less breathable on their own than this combination of a 3M Aura and these covers. YMMV since mask fit is very individual.
Here's a link to the original testing I did with the earlier version of these same fabric covers:
