In skiing and snowboarding, taking the fall line refers to the line down a mountain that is most directly downhill - inspiring the cylindrical lens styling of this model. The Oakley Fall Line L Prizm Snow Sapphire Iridium adult winter sports goggles offer a large field of view and a rimless frame. Designed for large-sized faces, those alpine ski goggles are engineered to integrate perfectly with most protective helmets. And the Sapphire Iridium® lens features the PrizmTM Snow technology providing maximal contrast and enhanced visibility while protecting your eyes against the UV and reducing glare, perfect for alpine conditions in sunny or cloudy weather. Also, a storage microbag that can also be used for lens cleaning is included.
