QUICK CHANGE LENS SYSTEM — The Quick-Change Lens System uses self-locating magnets to assist in lightning-fast lens replacement. Four snap pins keep the lens securely locked in place. EXPANSION VIEW (EXV) TECHNOLOGY — Perfected at Giro's test lab in Scotts Valley, California, this groundbreaking new Strap design serves up unparalleled peripheral vision. We started with a helmet-compatible goggle, and then shaved down the Strap rim and added FRAMELESS zones to optimize a massive spherical lens focused on the best possible peripheral vision in a goggle. EVAK VENT TECHNOLOGY — Found exclusively on VIVID goggles models, 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. SEAMLESS COMPATIBILITY — For optimal performance of both helmets and goggles, Giro products are designed to work together, ensuring a seamless interface between helmet and goggle for an exceptional fit and dependable, worry-free function. INCLUDES - Giro Contour RS Ski Goggles with Camp Tan Cassette Strap, Vivid Smoke Lens (28% VLT- Mixed Clouds), and Vivid Infrared Lens (50% VLT- Overcast/Storm) 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 ZEISS, and you're more than ready to shred in all conditions.
