Won't fog up your glasses
This is the only face mask that i can get to hug my face enough without fogging up my glasses. Often i just use my 3M full face but it is way too hot in the summertime.

Good dust mask
If you wear glasses, don't even consider a mask without an exhalation valve like the one found on this mask. When I first received these, I was expecting the soft, but semi-rigid style (which can also be obtained with the exhalation valve). These come folded into thirds and are unfolded to use. I've since used both and to my surprise these fit me better. They are also easier to store and are individually wrapped, which keeps them clean until used. They have a small bendable strip which you conform to the bridge of your nose.Like all dust masks, they are not perfect, but probably the best I've used. They are conveneinet and leak less - and the valve greatly reduces eyeglass fogging.
does the job
I like the soft nose piece, but the smell that is initially present when you first put it on is unpleasant. Other than that, it is small and out of the way. Your face doesn't get all sweaty when you use it.
