Very comfortable, seems to be good quality
This seems to be a good face mask, thick enough to be protective but still very comfortable.  I've worn mine for as long as 3 or 4 hours doing activities outside the house and have had no problems with discomfort. The medium size fits both my husband and myself very well. One negative is that the mask will cause glasses to become fogged in a way that does not happen with the masks that have an adjustable nosepiece. Also, I've noticed that if I'm exerting even a little bit, like say walking briskly up a steep hill for several city blocks, I can't get get enough oxygen and have to open up the bottom of the mask for a minute or two so I can breathe!  Although this is an inconvenience, it probably shows the mask is filtering well and working to protect me as well as others.
