The thing with masks is that if they're not a bit constrictive, they probably don't work (except for face shields, but who wants to look like a welder with a transparent shield?). That's the nature of filters. Having said that, there's constrictive, and there's *constrictive*. I should say that none are constrictive to the extent claimed by anti-maskers.
I find the least constrictive is one that has the largest surface area and that also does the job. Duh! But *how* do you know if it does the job? Given that masks are at least half a prophylactic against transmission to *others*, an easy way of determining efficacy, without specialized tools, is to try blowing out candles that are within a few inches of your face, with the mask on. If you can blow out said candle, the mask isn't effective enough. Stay away from the N95 masks with one-way valves; sure, they're nice for you, but they do not mitigate the dispersion of droplets to others as you exhale. Anyway, I find buffs, wool ones, double-layer-up, and merely lightly snug around the mouth+nose instead of tight, to be efficacious and least constrictive. In fact, I use that when cycling in cold weather. With the proper eyewear, I don't experience fogging issues when on the move. In addition, you may also want to look into anti-fog treatments, especially as eyewear will fog up even without masks when one suddenly stops, in between exertions.
