Review (4/5): love the look, but they do stretch slow and you have to pull them up a bit.
I got these for the stores that require masks. Great when it was cool, than can be a little warm on hot days. Also noticed, they do strecth a little bit after time and lose their ability to stay up by themselves. Work around it just to double it over a bit.
I love the flag look, and they function as required.
