The SMITH Cariboo OTG Ski Goggles offer exceptional fog protection, optimal comfort and a perfect fit for eyeglass wearers. The classic teardrop style of this goggle has been specifically designed to be compatible with goggles and helmets. It fits medium-sized faces and is designed to eliminate the gap between the mask and the face while leaving enough room for prescription glasses behind the lenses. This comfortable goggle uses active ventilation to prevent fogging when weather conditions and speed change.
