Airfly AF-301BK Photochromic Performance Eyewear
The AF-301BK is engineered for cyclists who demand both performance and comfort. The “BK” stands for BIKE, reflecting its design tailored specifically for the demands of cycling.
Its vertically extended lens provides an unobstructed field of view, even when leaning forward in an aggressive riding position, while the horizontally extended design reduces side wind drag for a smoother, more aerodynamic ride. Every detail is crafted to enhance clarity, stability, and performance on the road or trail. These photochromic lenses seamlessly adapt to your environment, darkening under UV light for effortless glare reduction, and returning to crystal-clear transparency at night—perfect for protecting against wind and insects during evening rides. Enhanced with a precision anti-reflective (AR) coating on the back, they minimize distracting reflections and deliver an uncompromisingly clear, comfortable view. Every detail is engineered for riders who demand both elegance and performance, day or night.
