Serengeti introduces its newest, most advanced driver's lens in its
lineup: the Strata 400. The Strata 400 is polarized with patented spectral control filters to
absorb ultraviolet radiation better than the untreated glass used on many sunglasses. The Strata
400 is available in four Serengeti frames: Argosy, Milos, Epiros and Iliad. Prices start at
$199.99.
