Magna Tech quick lens change technology anon Spherical lens technology Wall to Wall vision Full perimeter channel venting ICT Flush mount outrigger Triple layer face foam Lightweight TPU frame Spare graybird lens included 10x12x21 nylon compression molded goggle case included Micro fiber goggle bag included Fit - Frame height 96mm High-performance riding demands the best possible field of vision. Wall-to-Wall incorporates optimal optics, low-profile frames and 40% thinner face foam, producing an ultra-close fit that eliminates the peripheral vision impairments of typical goggle construction. The result is a truly unobstructed viewing experience. M2 Magna-Tech integrates 16 rare earth magnets into the carrier liner for 8 total points of connection, each with a pull force of 2.75 lbs. (Total Retention =22 lbs.) - the pinnacle in retention with self-aligning engagement. anon. ICT (Integral clarity Technology) delivers crystal clear vision, no matter what the elements throw at you. Starting with a porous cellulose inner lens surface for superior water shedding above and beyond standard acetate lenses, we apply or chemically etched ICT anti-fog treatment for long lasting clarity. ICT works in tandem with Full Perimeter Channel Venting to evacuate warm, moist air from the lens area. anon.s Spherical and Cylindrical lens constructions are both injected, not stamped, to eliminate optical distortion. Our Spherical lens construction combines de-centered technology with a lens curvature that mimics the curvature of the human eye for superior optics. Cylindrical lens construction utilizes de-centered injection technology, which tapers to a thinner profile on the edges for reduced peripheral distortion.
