Inspired by Oakley's first true oversized snow goggle, Canopy, the new Flight Tracker S has a classic, stylized shape, and an oversized full-rim toric design with an optimized field-of-view in all directions. Flight Tracker will fit a wide variety of faces and is engineered to integrate perfectly with most helmets, this model comes in a small/youth fit, suitable for ages 12-16 years. Prizm lens technology has been specifically engineered to enhance visibility and contrast over a wider range of light conditions. F3 Anti-fog lens coating prevents moisture build-up keeping your vision clear. With High Definition Optics (HDO), the lens is cut thicker over the optical centre and thinner towards the edge, helping eliminate any distortion. High-grade Plutonite lens material is engineered to give clear, sharp, and accurate vision while offering protection against impacts. The flexible O Matter frame conforms to the shape of your face. Silicone backed strap keeps the goggle securely in place, even on a shiny helmet surface. Triple-layer polar fleece foam creates a solid yet comfortable/dry fit.
