Val Kilmer was a Serengeti brand ambassador in 2005. Among the sunglasses he was endorsing, are the Serengeti Nuvola sunglasses, as seen in the promotional photo on the left.

These Serengeti Nuvola sunglasses are just as much at home on the water or the road as they are in the air. Choose a gradient lens, preferred by pilots because they block harsh glare from the sun above, while providing a clear view of instruments below. Or select non-gradient lenses for uniform, top-to-bottom protection against sun and glare. No matter what you're piloting, Aviators with Serengeti's advanced photochromic lenses minimize fatigue and eye strain from the sun.
