Yep, a bunch of people still vouch for double masking since it was popularized by the CDC. However, its results are highly inconsistent, averaging out to a wash much of the time, because it's very difficult to get both in the same position every time without shifting/crushing the mask underneath.

That said, that's just what my reading and research has found for me, so I choose a single high-quality N95 rather than any mix of double masking.

You may have found different.
