Why Do Cyclists Choose the KOO Alibi Sunglasses? The KOO Alibi is a half-frame performance sunglass built for riders who want precision optics and a secure fit that holds through every sprint, climb, and switchback. The half-frame construction opens up your field of view while ventilation holes in the lens eliminate fogging during hard efforts, keeping your vision clean whether you are in the drops or out of the saddle. MEGOL elastomer on the temples and nose bridge grips skin as you sweat, holding the Alibi precisely in place without any mid-ride adjustment required. Engineered with a unisex fit that accommodates both male and female facial geometries, the Alibi features rounded arms and reduced temples that align cleanly with helmet straps without creating pressure points over long hours in the saddle. The photochromic lens option automatically adjusts tint as light conditions shift, removing the need to swap lenses mid-ride, while standard mirror variants deliver bold color with proven UV protection. A go-to performance eyewear pick for road and gravel riders who expect every piece of kit to earn its place.
