ENDURA Pro SL Photochromic Sunglasses | Adaptable High-Performance EyewearExperience the pinnacle of adaptable eyewear with the ENDURA Pro SL Photochromic Sunglasses, engineered for cyclists and athletes who demand uncompromising performance in all conditions. These glasses offer the ultimate in versatility, providing crystal-clear vision that automatically adjusts to changing light, allowing you to focus purely on your performance. Whether you´re breaking away on a sun-drenched road or navigating technical trails in the shade, the Pro SL sunglasses are your essential partner for clarity and protection.The standout feature of the Pro SL is its revolutionary adaptability. The premium design features a removable lower frame, allowing you to seamlessly convert the sunglasses from a robust full-frame style to a minimalist, lightweight half-frame configuration in a matter of seconds. This gives you the power to choose between maximum protection and enhanced airflow based on your ride, conditions, or personal preference. This customisation is achieved by simply swapping the lower N66 frame bar with the included adjustable nose pad.At the heart of these glasses is the advanced, high-definition photochromic main lens. This single-piece, light-reactive lens intelligently transitions from a lighter to a darker tint (Category 1-3) as the ambient UV light increases, ensuring optimal visibility without ever needing to switch your eyewear mid-activity. The cylindrical profile provides an expansive, uninterrupted field of view, while a flash mirror finish reduces glare. Engineered for the real world, the lens features a super-hydrophobic front coating that sheds water and spray, and a highly effective anti-fog back coating to maintain clarity during intense efforts and humid conditions.To ensure you are prepared for any scenario, the ENDURA Pro SL comes as a complete performance package. In addition to the main photochromic lens, you receive two supplementary interchangeable lenses. The REVO coloured mirror lens is perfect for exceptionally bright, bluebird days, while the amber lens significantly enhances contrast and definition in low-light situations like dawn, dusk, or heavily overcast rides. This comprehensive three-lens system guarantees you have the perfect optical tool for every possible light condition.Attributes: Adult, Photochromic, Photochromic 1-3, SyntheticTechnical Specifications: Premium adaptable eyewear with removable lower frame, inter-changeable cylindrical lenses.
