3-Ply but breathes like a 2-Ply
Use for Fog and haze weather,Gray sky,Fog weather, Dust weather, Snow weather, Building site Etc.Not for Medical use. It has 3 layers and covers my whole face. I feel like it will protect me and those i come in contact with; and the price was right.  The ear loops are comfortable and the nose piece keeps my glasses from fogging.
