The Cornea Blue/Blue ski goggle has the lens attached to the outside of the frame resulting in a larger field of view. In addition POC has incorporated very high end materials to make sure the goggles do not fog. Good Vision + No Fog + Cool Styling = POC Cornea. The Cornea Blue/Blue ski goggle comes with POC’s Clear/Gold Mirror lens. 55% of the light is allowed through this neutral lens and a multi-layer gold coating is added to increase visual definition in all light conditions. Add the Skull X Blue ski helmet to the order for great comfort, and styling.
