Goggles keep you fog free in most humid environments - ESS Profile TurboFan Anti-Fog Tactical Goggles

These goggles stood up to the challenge of a Miami summer which is about as humid as it comes. They don't fog. Field of view is great, I like the ability to swap out lenses. Down side is the fan makes some noise. So I don't recommend them for hunting or other work which must be real stealthy. Also compared to other goggles they are a little bit heavier so if you wear them for longer periods you are going to feel it.
Pros: Good optical quality on the lenses, work as advertised
Cons: fan makes some noise so not for times when you must be totally quiet, and they are a bit heavy
