KOO is the independent eyewear brand of the Italian helmet manufacturer, Kask. Koo's genesis comes from 2017 with a single offering in the form of the OPEN, a full-frame sunglass that featured an innovative arm-folding system and optically accurate lenses from German market leader Carl Zeiss.
The large composite frame accommodates a wide, single Carl Zeiss lens that provides an incredible panoramic view with unparalleled optical sharpness. The leading anti-reflective technology used by Zeiss significantly improves the efficiency of the lenses. The coating eliminates reflections from the front and back surfaces of the lenses, meaning your eyes receive the greatest possible light, contrast and definition are improved and eye fatigue is reduced.
Being performance oriented glasses, the new Demos have a well thought-out ventilation design to combat the dreaded fogging. The frame is reinforced in several 'recesses' where the frame sits behind the lens and where there are gaps between the lens and the frame at the bottom. Combined with 2 additional vents on the top of the goggles, this construction ensures that airflow between frame and lenses is maintained and the rider's vision remains crystal clear. By integrating the ventilation in this way, it also contributes to the overall aesthetic in a typically Italian way.
Like most KOO goggles, the Demos come with the company's 2-position adjustable nosepiece for adjusting your fit and comfort. In addition, the frames have non-slip MEGOL elastomer temple inserts that provide extra grip and comfort, especially when damp from sweat or rain.
