With a slightly smaller frame and lens than the original Contour™, the Contour™ RS offers almost the same impressively large field of vision and is therefore perfect for smaller face shapes. The new shape, combined with Expansion View Technology+ and VIVID lenses, allows for clear and distinct visibility of all elements on the mountain. Additionally, the Contour RS features the EVAK ventilation system, a VIVID infrared replacement lens for poor weather conditions, and an extremely efficient lens quick-change system.
