This mask is good for low humidity type day's. It is a pretty good mask for its price. It is very good in the winter time.This mask is always dependable eccept for the high humidity days.Doesnt scratch easily , or slips off .
If the humidity is high expect it to fog . There is nothin really bad about it besides the fog part.
I think that this product is very good , but if you live down south were there is alot of humidity then this wouldnt be for you.But northerners would like this product do to the fact that they have dry colder winters
