"I got these cause a lot of reviews said that these wouldnt fog, and one even said they were in florida and they didnt fog. Well, i haven't played in a skirmish with these yet but they don't seem to resist fog that well. i live in florida and it is rather warm right now even though its getting colder, but i can go out for a short target practice session and before i'm finished i have to take the goggles off. not really impressed. they are, however, rather comfortable to have on. special note: i am known for sweating pretty easily. so, if you know you dont sweat easily and you live in less than warm climate, then these might be gold for you. but for me, they fog too easily which is why they only get 3 stars."
