Knowledge OTG, Black Frame, Blue Sensor Mirror Lens

They never take clear vision for granted. The Smith Knowledge OTG goggles are over-the-glass and optical docking station compatible (ODS). In other words, you can wear them over your prescription glasses or use their ODS prescription lens insert to maintain the sharpest vision possible. The regulator adjustable lens ventilation keeps the air flowing for consistent fog-free performance. Add a pressure-free fit around the temples, and you've found the goggles for skiers and riders with prescription lens needs.
