Block out the breeze with the Airlock 1 made of gloss black Grilamid TR90 frames, which are lighter, more flexible and significantly more durable than conventional plastics. The lenses are shatter-resistant polycarbonate, which provide 100 percent UVA and UVB protection, and the streamlined, wrap around frame is extremely comfortable. The included detachable side shields reduce air draft by as much as 95%. The lenses are interchangeable and come with gray, clear, and orange lenses. Comes with a limited lifetime warranty, a zipper carrying case with a clip, and a cleaning cloth. Measures 35mm tall, 154mm long, and 125mm wide.
