FAQ

What is the difference between the KOO Alibi Regular and Large fit?

The Regular fit is the standard Alibi frame sized for average facial geometries across both male and female riders. The Large fit version scales up the frame dimensions for broader facial profiles. If you have found standard cycling sunglasses tend to sit too close to your face or feel narrow, the Large fit is worth considering.

Is the photochromic lens worth it on the KOO Alibi?

For riders who train at variable times of day or in regions with unpredictable cloud cover, the photochromic option is a strong choice. It eliminates the need to carry a second pair of glasses or swap lenses mid-ride, automatically darkening in full sun and lightening as clouds roll in.

How does the KOO Alibi hold up during high-intensity efforts?

The Alibi was built specifically for this. The MEGOL grip system on the temples and nose bridge maintains contact as sweat builds, and the reduced temple design eliminates the pressure points that cause conventional sunglasses to shift during sprints or out-of-saddle climbing.

Best For

Road and gravel riders who prioritize fit security and unobstructed vision over long miles. The KOO Alibi Regular is a smart pick for cyclists who log serious training volume and need eyewear that performs from the first pedal stroke to the last, without thinking about it.
