Zipline XT features RipClear lens protection film for hours of clear vision on the mountain. Combined with our Italian made inner lens for perfect clarity. The new cylindrical lens offers a panoramic view and the XT (Extra Terrestrial) shield look provides not only a cool look but a massive field of vision. With 7 strategically placed magnets, with increased strength over previous models, switching lenses is easy yet allows you the security of smashing through the bumps or floating in powder. See why athletes like Canada Ski Team athletes like Kerrian Chunlaud & Simon Limeuix have switched.
