Last winter, I even bought a mask from https://zerofogmask.com/?v=7516fd43adaa, which you heat up with a hair drier before wearing for the first time so it molds to the shape of your face. It admittedly worked better than a normal mask, but only partially and only for a few uses, which wasn't economical at $20 each. Plus, it was particularly uncomfortable.
