In the end it's all about fit. If you can do a home fit test on your mask of choice I highly recommend it. Most people will recommend against double masking, but, I will say that in my case the best fit I ever found was a particular N95 with a neck gaiter and I'm sure that wouldn't be the same for everyone.

I'm also a weirdo who in the early days when N95's weren't available and everyone was wearing cloth masks I bought layers of electrostatic polypropylene and jerry-rigged my own masks, so, I'm not against messing with it to make it right.
