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 Photochromic Fuchsia Mirror lens, giving the Alibi a broader usable range across changing light conditions. The cylindrical Zeiss® lens is tuned for clear, precise vision and full UV protection, while the photochromic lens shifts from Category 1 to 3 with a VLT range of 75–12%. Hydrophobic and anti-scratch properties add durability and performance in mixed conditions, and the included bridge nosepad helps fine-tune fit.
