We used lightweight and durable C-5 alloy to put a new twist on originality with distinctive stem architecture, and laser etching let us create a faux lens rim line that's both minimalist and modern while spring hinges and air-filled silicone nose pads keep comfort dialed in. Whether you choose the lens shape of Tailpin or Tailhook, you'll have a fresh look that's smooth with style, along with the secure grip of Unobtainium earsocks in a Three-Point Fit that keeps the optics in precise alignment. Our pure Plutonite lenses filter out all UV while High Definition Optics maintains clarity at all angles of view, and the range of available editions lets you choose options like premium HDPolarized lenses to filter out harsh glare, and Prizm technology that dramatically enhances contrast and visibility over a wide range of light conditions.
