Can be very good with some modifications
Good quality double t-shirt material. Seems well made and large size fits large man with medium beard. Covers from bridge of nose and over chin to almost neck. Has a filter pocket.<br />There are some flaws as delivered. There is no bendable wire at the top so fit on nose is very loose. However, there is sort of a tunnel at the upper seam that is sewn closed. You can puncture that tunnel and slide in a pipe cleaner or metal tab to get a better fit at nose. I also was able to slide a 3M N95 mask with valve into the filter pocket to increase protection. Lastly the loops kept pulling the tops of my ears down. I resolved this problem by loosely secured the left and right upper bands of the ear loops behind my head with an elastic band and the mask fits more comfortably. I slip the upper bands over the top of my head and then tighten up the lower ear bands for a very secure fit. Sorry that I don't have pics but you should be able to figure out the modifications.
