This advanced optical technology is engineered to dramatically reduce glare from reflective surfaces such as water, asphalt, and snow. By filtering out distracting horizontal light, the lens enhances definition and color contrast, allowing you to perceive your environment with exceptional sharpness and depth.

All styles in the K3 collection count on our DrySky+ ventilation system to guarantee excellent vision in any situation. Strategically placed air vents in the lens and frame promote continuous airflow, effectively preventing the lens from fogging up during strenuous exercise or in humid weather, ensuring your sight remains clear when it matters most.Your investment is protected from the moment you receive it. This product includes a PU hardshell case for secure storage, a microfiber pouch that doubles as a cleaning cloth, and replacement rubber bands for temples and nose pad to ensure a perfect fit over time.Adapt your K3 sunglasses to any light condition or need.
