Wipe down the inside of your goggles with this and it will help keep your goggles from fogging. It doesn't last forever of completely eliminate fogging, but will help. I noticed that the treated goggle lenses get blurry when they are just about to fog over, but still keep the trail more visible for longer than normal before they finnally fog up. Also once you do fog up the goggles, a quick re-application will get rid of the fogging again for a while. I like to carry one of these with me in my pack on the trail and occasionally re-treat and clean my goggles when I stop for a break.Read All Reviews
