Running through the forest, diving on the speedball field, and ducking for cover can mean bad news for you paintball mask.  For those of us who tend to put off a lot of heat when they are on the paintball field, having ant-fog spray, a thermal lens, or even a thermal lens with anti-fog spray/gel isn't enough to keep it clear.

Now, however, there is a solution to fog and heat control behind the mask.  Paintball masks with built in fans to blow away the heat. Having a mask with a fan is a great way to keep cool and fog free when things heat up.
