Summers are hot in Orlando as you know. We wear the disposable surgical masks in and out of grocery stores, but by the time we are done with say a 45 minute to 1 hour shopping trip, then walking outside in the heat to the car, when at times, heat index is say 106, its hot, my face is sweating by the time we reach the air conditioned car. Many do say that the air flow is better on the disposable ones, versus cloth.
I have read and watched medical professionals on the news speak about not pulling masks down on the neck, like a gaitor type mask, since there are bacteria on your neck. September is still hot here.
