This is the best fitting mask and it doesn't fog up your glasses.
I love these masks.  I have tried numerous brands and they do not fit well, fog up, etc.  These are wonderful.  I have washed mine in the washing machine very frequently.  I am ordering two more so I can get through the week with them.  They are also very beautiful and well made.  I order mine with the metal nose strip so I can form it to my face and the glasses don't fog up.  I have to wear it for about 9 hours a day and it is comfortable.
