If you're like me and you wear glasses and are tired of them fogging... well you need to get yourself a 2.0 Dark Venomous Sleeve. I love that it's comfortable and provides and snug fit (keeping just about everything out... PLUS my glasses don't fog up, like with every other mask that I've used during this pandemic. Hint: I also use the 2.0 Filter Inserts. [This is my 2nd only because the first got lost during vehicle accident]. Get one!
