The KOO Nebula is a frameless performance sunglass designed for athletes, adventurers, and life on the move. Weighing just 21 grams, it delivers feather-light comfort with a secure, no-slip fit for every challenge. This version uses a Photochromic Graphite Mirror lens, giving the Nebula a wider usable range across changing light conditions while keeping the same clean, minimal silhouette and wide toric field of view.
The frameless construction keeps the feel light and unrestricted, while the photochromic lens shifts with the conditions, moving from Category 1 to 3 with a VLT range of 73–14%. That makes it a versatile option for cloudy rides, mixed light, and intense sun in one setup. A low-bridge nosepad is also included in the box for added fit flexibility.
