Serengeti Palladio Sunglasses for Men embody the spirit of the Flex series, with an optimum level of comfort, durability, and personalized fit. These contemporary Serengeti sunglasses showcase excellent shape memory through their supple Infiniflex frames, which use an elastic metal alloy to conform to the contours of your face. This close and customized fit is improved further by the Palladio's adjustable nose pads, which allow the sunglasses to fit almost any face shape. The Serengeti Palladio Polarized Sun Glasses are comfortable, but they also sport some of the most advanced lenses in Serengeti's repertoire: Polar PhD lenses. With Polar PhD, these polarized sunglasses will adjust for changing light conditions (photochromic), cancel out glare and too-bright colors (polarization), and create optimum color saturation and contrast (spectrum control) for an unfettered, true to life image that is actually improved over what you see with your naked eye. Serengeti's proprietary oleophobic, hydrophobic, and hard coat lens coatings keep the lenses free of dirt, oils, and scratches for long-lasting performance. A thin, full-frame design with an ergonomic double bridge keeps the Serengeti Flex Polar PhD sunglasses sitting lightly (and securely) on your face. Why conform your style to a pair of sunglasses when the Serengeti Palladio Men's Shades will conform to you?
