Made with eyeglass wearers in mind, Smith's Option OTG fits over most glasses and helps eliminate fogging. All-day comfort is ensured with Smith's F.A.T. double-layer face foam and strap outriggers that distribute the pressure evenly. Included with these great goggles is Smith's Roll Offs system, so you'll always have a clear view without the mess of a tear off system. You'll also love the scratch-resistant, anti-fog Lexan lens. A silicone strip inside the helmet strap keeps these awesome goggles in place, while plenty of vents inhibit fogging when the pace or temps heat up.
