The Atomic Four Pro HD Retro ARC goggle is a special, limited-edition ski goggle with a retro design inspired by the 1991 World Championships. It was created to pay tribute to Atomic's 70 years of racing. Beneath the design, the technology is as advanced as it gets: HD Lens Technology, microcrystals in the lens split light into 6 spectral colors, enhancing the blue and red layers for incredible depth perception and visibility in all light conditions. The cylindrical double lens is combined with a wide fit, while the sealed lens system protects against wind and water to eliminate condensation and fogging, and makes lens replacement easy. The Live Fit frame adapts to your face for an individual, personalized fit, and the OTG Lite grooves in the frame are compatible with prescription lenses.
