EXFOG ®

ExFog is made by Battlewear Components, a U.S.-based company that took a different approach to solving lens fog than the traditional spray-and-wipe method. Instead of a chemical coating that wears off mid-game, the patented ExFog system uses a small, rechargeable fan mounted to the temple of your goggles that continuously pushes air through tubing across the lens — regulating temperature and preventing fog before it ever forms. It's currently the only self-contained, mounted anti-fog solution of its kind on the market, which is why it's become popular not just in airsoft but in paintball, skiing, and other high-humidity, high-exertion environments. If foggy lenses have ever cost you a game, this is the fix that actually holds up for the full match, not just the first few minutes.
