Serengeti Azione Men's Sunglasses are a sporty pair of aviator sunglasses with a classic, no-frame look and comfortable style that can keep up with your high speed lifestyle. Part of the Serengeti Sport Polar PhD series, the Azione utilizes Polar PhD lens technology, which combines photochromic, polarized, and spectral control elements to enhance color, contrast, and glare reduction. The lenses of the Serengeti sunglasses are finished with a double sided hard coating for scratch resistance and an oleophobic and hydrophobic coating to prevent smudges from fingerprints, debris, and water from getting a foothold on the lens, keeping your vision unobstructed and crystal clear no matter where your travels take you. Serengeti has incorporated Megol temple tips into the Serengeti Sport Polar PhD Azione Sun Glasses, which improve their grip as you sweat, making the sunglasses more stable when you're more active. Adjustable nose pads allow you to tailor the fit of the sunglasses to your face for custom comfort where you need it most. The streamlined, slightly curved style of the aviator sunglasses fits small and medium faces exceptionally well, and the no-frame design sits lightly on your face without dominating your features. Built for sport but designed for style, the Serengeti Azione Polarized Shades are ready for your next adventure.
