The Giro Contour Goggles will have you feeling like a fighter pilot as you are charging down the moutain! How do they do that you may ask? Well Giro has given the Contour Goggle their largest field of vision thanks to their EXV+ (Expansive View) Technology. Pair that with their Vivid lenses by ZEISS® and you will see everything on the trail and around you. The lenses are Toric Spherical in shape which will mimic the curvature of our eyes. This model provides extra cushioning around the nose bridge for a better fit. The Giro Contour Goggles will fit perfectly with any Giro helmet to give you the ultimate clean look. As a bonus, each goggle comes with a low-light VIVID infrared lens.
