The KOO Alibi is built for every ride, delivering sharp vision and all-day comfort on road or gravel. Designed to stay secure through climbs, sprints, and switchbacks, it combines advanced optics with a no-slip fit that feels stable and dependable when the pace rises.
This version uses a Gold Mirror lens for bright and intense sun conditions. The cylindrical Zeiss® lens is designed for clear, precise vision and full UV protection, while the lightweight construction keeps comfort high over longer days out. Hydrophobic and anti-scratch properties add durability and performance in changing conditions, and the included bridge nosepad helps fine-tune fit.
