Perfect!!!
My techs love using these. They have full beards and are very comfortable wearing these. Other masks, they can only wear for a little time. These are able to be worn much longer.

poor design
This mask has a valve that lets the wearer expel breath outward, thus not providing much protection for those around them. While it makes it easier for the one wearing it to breath, it doesn't seem safe for others around. The stings are quite narrow and uncomfortable by digging into my face, head, and chin. I wont be ordering any more of these.

Nice N95 mask with braided straps
I recently developed an allergy to the elastic straps on some of the 3M N95 model masks, and was relieved to discover this N95 mask with braided straps. In addition, it is built with a significant bulge that makes breathing easy. It is a bit large - not too large for my face, but it comes very high near my eyes. Also, the straps attach with staples, and I was worried ...

Excellent for a person w/ glasses
Directs exhalation away from glasses on cold days, reducing foggy glasses.

Strap is too short - makes the mask uncomfortable
It seems like its a one size fits all - but it isn't! If you are willing to modify the strap it will provide the seal around the nose and mouth comfortably

They are good. Comfortable but a bit tight specially for those with big heads.

Cool and comfortable
For a mask that actually fits correctly (tight to the face), it is very comfortable. The vent keeps the mask from becoming hot and sweaty when worn for hours. I wear glasses and the metal nose piece when adjusted properly keeps air from escaping and fogging up my glasses. However, the straps can start digging into the skin. I started wearing a baseball cap and had t...
