Giro's Index OTG Goggles are over-the-glasses goggles designed for skiers who'd rather not ski with contacts frozen to their eyeballs. Their lens has an anti-fog coating to clear moisture, but the same cannot be said for your glasses. Giro designed the frame to fit their helmets seamlessly, thereby avoiding the dreadful gaper gap. Two layers of cushy foam offer a secure seal against your face, and the microfleece lining feels smooth against the skin.
