Smith Knowledge OTG With Fan

Like new condition rarely used - one very minor exterior lens scratch. When you’re smack in the middle of a week-long heli trip and going deep daily, the last thing a glasses wearer wants is to spoil the vibe with cloudy vision. Increase your chances of a successful mission with the Smith Knowledge Turbo Fan OTG Goggles, the ultimate weapon in the fight against fog. The Knowledge Turbo Fan’s deep volume fits most eyeglasses, and combined with Smith’s 5X™ anti-fog lens coating and two-speed turbo exhaust fan, it takes some serious yard sale action to bring these goggles to a halt. If you wear glasses and like riding powder, don’t leave home without these. Frame Large fit to accommodate glasses. Lens Cylindrical Carbonic-X Lens 5X™ Anti-Fog Inner Lens – The most advanced anti-fog lens ever created, engineered to provide over five times the absorptive properties of anything on the market. TLT (Tapered Lens Technology) – Visual distortion occurs when light waves hit an aggressively-curved lens causing it to bend or distort an object’s true size or position. Tapered Lens Technology corrects the distortion by progressively tapering the lens from the optical center towards the outer edges. Light waves are thereby delivered straight to your eye resulting in zero distortion and true optical clarity. What you see is what you get. Carbonic lenses are engineered to be the most impact resistant lens material in the world. Injection molded with Tapered Lens Technology for optical precision and a high level of protection. Patented Porex™ Filter – Prevents optical distortion due to changes in elevation by allowing air pressure within the sealed lens chamber to equalize with the ambient atmospheric pressure.
