Welcome to the dark side. The ULTRA Black lens has the tint (VLT) cranked down to 6%, compared to industry standards of 11% - These lenses are DARKER and legally should not be used when operating a vehicle. On the other hand, these are the ultimate bright outdoor lens. Whether you are on the snow, sand, a white rooftop or just want the ultimate poolside shark lurking lens these are for you. Aptly named after big-engine, afterburning interceptor fighter aircraft from the 60's and 70's, the Interceptor sunglasses are a step up in every regard. Every detail of these sunglasses was meticulously gone over to ensure the final product was something that we could be proud of, and something that could sit right along side high-end counter parts. The Interceptor spins our classic Regulator frame by adding a high-polished wire frame, and a metal brow bar for a modern take on the classic full wire aviator. The matte black polycarbonate frames are a prefect contrast to the brilliant metal surfaces making for a pair of sunglasses that not only raises the bar for Heat Wave Visual, but for your own personal collection as well.
