Same here. I've been taking the pandemic 100% seriously ... but this sudden call for double-masking just feels like something that's trendy, not grounded in epidemiological statistics.
I know the CDC has now updated their guidance regarding double-masking. But we know know that some folks in charge of health guidance like to kind of ... I don't know how to phrase it ...
couch their guidance in over-reaching foolproof terms? The idea is to get even people who are looking to skirt the rules (e.g. people who were wearing stretched-out single-layer sheer gaiters last summer and calling that good) to reach sufficient compliance despite themselves.
Anyway, my family last night went to visit my sister-in-laws family in their home. They're a lot looser with COVID protocols than we are, so we all double masked. My wife and two kids did the surgical mask under a double-layer heavy cloth mask (think chino-pants material, doubled) while I wore two double-layer heavy cloth masks. Double-masking seems to generally take care of the mask-gaps issue that seems common with many surgical masks and ill-fitting cloth masks -- so in that sense, wearing a second mask to "tighten things up" can be a good thing.
On the other hand, a well-fitted double-layer mask should be A-OK by itself (per the new CDC guidelines) ... but many people are interpreting "double-masking" as "always wearing two masks no matter how they're made or how they fit".
