Smith Knowledge OTG turbo goggles are designed to fit over your eyeglasses - hence the OTG meaning "over the glasses"). Available in two colors, Smith Knowledge OTG goggles are fantastic for skiing. The turbo version of the Knowledge OTG goggles includes a fan to keep a constant air cirulation in the goggles. This prevents them from fogging up when you are standing in the lift line, or sitting in the chair.
The best fog prevention system available for eyeglass users.
