The Spy Marshall 2.0 Night Rider / Silver + Clear adult winter sports goggles feature a spherical dual lens that mimics the geometry of your eyes to reduce fatigue and distortion. Featuring a wide field of view and the HappyTM lens technology, those sleek alpine ski goggles are comfortable and provide an improved vision. Their wide strap creates an improved fit, while their RISE™ ventilation system creates a vacuum effect that pulls hot air from behind the lens and quickly releases it to be sure your vision stays free of fog throughout your ride. Those goggles present a VLT (Visible Light Transfer) rating of 18% which gives you superior protection when the sun is bright.
