Fog doesn’t stand a chance with our bestselling 509 Kingpin Ignite Goggle featuring heated lens technology derived from the same science used in military aircraft windshields. Simply push a button and the lightweight, strap-mounted rechargeable lithium-ion power pack quickly heats the entire inner lens surface to 104°F. The system features a 2-minute mode or ‘always on’ mode, along with a continuous runtime rating of up to 5 hours at max temp for all-day clarity.
