The future of anti-fog goggles has arrived! Introducing the Ignite heated dual lens technology by 509. Available exclusively on our Sinister X5 & Kingpin goggles, the Ignite heated lens provides the ultimate in fog prevention technology. Fueled by a lightweight strap mounted 7.4V 2200mAh rechargeable lithium-ion power pack, the entire surface of the lens quickly heats up to 104° F using a transparent thermal conductive ITO (Indium Tin Oxide) layer on the inner lens. Evolved from military aircraft windshield defrosting technology, the Ignite quickly eliminates fog with a single button in either two minute auto mode or ‘always on’ mode. A continuous run time rating of 4-5 full hours at max temp ensures you are fog free all day. Simply recharge the pack for tomorrow’s ride. The power pack features integrated Bluetooth technology for battery status, firmware upgrades, and to create customized heating profiles that fit your specific needs.
