The CLK goggle is named after Dye’s innovative "click" lens attachment system that allows riders to change their lens in seconds with the click of a hidden release button. Lens changing has never been easier! The CLK is a large fit frame featuring an expanded field of view, optimal helmet integration, and strategic venting for maximum breathability. Spherical lenses retain the highest optical quality, and provide 100% UVA, UVB, and UVC protection further enhanced by Dyetanium and 4D coatings that balance light transmission, stop glare, eliminate fog, and improve durability. All CLK goggles come with additional lenses for most conditions. It just clicks.
