With a new toric lens shape that&';s slightly smaller than the original Contour, the Contour RS goggle hits all the marks. The new shape, combined with Expansion View Technology+ and VIVID lenses, allows you to see all the features on the mountain with clarity, so you can spot takeoffs and landings with ease, while the quick-change magnetic-assisted lens system means more time riding and less time fussing with gear. Top that off with the EVAK vent system so you don&';t have to worry about fogging, and a bonus low-light VIVID infrared lens with Optics by ZEISSA(R), and you&';re more than ready to shred in all conditions. Anti-fog coating Expansion View Technology Plus (EXV+) Includes two VIVID Lenses with Optics by ZEISS - sun / all condition lens and low-light lens Triple-layer face foam with microfleece facing Adult Medium Frameless Design Toric VIVID lenses with Optics by ZEISS EVAK Vent Technology uses a new foam made from an ultra-durable, non-absorbent material. EVAK vents minimize the chance of fogging by releasing moisture while simultaneously creating a barrier from the elements.
