"Full Description:\nOakley®’s HSTN Metal showcases the original frame’s progressive design and heritage features of the first generation of HSTN while being in a league of its own. The original frame came to life after Oakley’s team of designers worked closely with friends of the brand in search of the next fresh take on lifestyle eyewear. The resulting sunglass with striking modernized circular lenses has now been evolved a step further with a wire trigger design. This special design pays homage to Eyeshade by replicating its unique aesthetic, originally created with a goggle lens and wire coat hanger. HSTN Metal also features Unobtainium® nosepads for the first time, providing unparalleled comfort and improved grip, while the BiO-Matter®* frame material gives the frame all-day durability. *BiO-Matter is made from bio-materials having at least 56% bio-based carbon content (representing ratio of castor oil to fossil sources) • DESIGN - Fresh take on a classic shape in a progressive design inspired by cultural undercurrents and with a nod to our heritage • FRAME MATERIAL - Lightweight and durable BiO-Matter® frame provides all-day comfort • NOD TO THE PAST - Modernized metal trigger stem design inspired by Oakley's iconic Razor Blade and made from metal in homage to the original Eyeshade prototype • NO-SLIP GRIP: Unobtainium® nosepads provide no-slip grip when wet to help increase retention • SEE MORE DETAILS - Available with Prizm™ Lens Technology designed to enhance color and contrast so you can see more detail • PRESCRIPTION READY - Available with Oakley Authentic Prescription lenses that come laser etched with the ellipse logo on left wearing lens for proof of Oakley authenticity.\n\nSpecifications:\n\u003cul>\n\u003cli>Lens Height: 48 mm\u003c/li>\n\u003cli>Frame Width: 131.1 mm\u003c/li>\n\u003cli>Arm Length: 142 mm\u003c/li>\n\u003cli>Lens Width: 52 mm\u003c/li>\n\u003cli>Bridge Width: 21 mm\u003c/li>\n\u003c/ul>\n"
