Endura Shumba II Photochromic SunglassesExperience the pinnacle of adaptable eyewear with the Endura Shumba II Photochromic Sunglasses. Engineered for the dedicated cyclist and multi-sport athlete who demands uncompromising performance, these sunglasses offer exceptional clarity, comfort, and versatility. Master every environment, from dawn patrols to sun-drenched midday climbs and dusky descents, with a single piece of high-performance eyewear.The standout feature of the Shumba II is its remarkable adaptability. The primary high-definition, cylindrical lens is equipped with advanced light-reactive photochromic technology, allowing it to automatically and rapidly adjust its tint in response to changing UV light. This means your vision remains optimized and protected without interruption, transitioning seamlessly from nearly clear in low light to a dark, protective shade in bright sunshine. For complete mastery over all conditions, the set includes two additional interchangeable lenses: an amber lens that enhances contrast and depth perception in low-light conditions, and a clear lens for essential protection from wind and debris during night rides or in bad weather.Customization is at the core of the Shumba II's design. The innovative adaptable frame allows you to switch between two distinct styles. Use it as a full-frame for maximum protection and a bold look, or quickly remove the lower frame to convert it into a minimalist half-frame style. This half-frame configuration increases ventilation and provides an unobstructed downward field of view, perfect for technical riding. The lightweight frame, combined with injection-moulded rubber temple-tips and a fully adjustable rubber nose-piece, ensures a secure, comfortable, and slip-free fit, no matter how intense the effort.Every lens offers a superior optical experience. The one-piece, cylindrical profile provides a vast and uninterrupted field of vision, while the high-definition quality ensures you see every detail on the road or trail with razor-sharp clarity. To maintain this perfect view, the lenses are treated with a super-hydrophobic front coating that causes water and spray to bead up and roll off, and an anti-fog back coating that prevents condensation during strenuous activity.Attributes:* User: Adult* Lens Type: Photochromic* Photochromic Range: Category 0-2Features:* Adaptable Frame Eyewear With Inter-Changeable Cylindrical Lenses And Removable Lower Frame* Lightweight TR90 Upper Frame Frame And Temples* Removable N66 Lower Frame Quickly Converts The Eyewear To A ½ Frame Style If Preferred* Injection Moulded Rubber Temple-Tips And Adjustable Rubber Nose-Piece* One-Piece, Cylindrical Profile, High Definition, Light-Reactive Vented Lenses* Photochromic Main Lens With Mirror Finish, With Super-Hydrophobic Front Coating And Anti-Fog Back Coating* Additional Amber (Low Light) And Clear (Bad Weather) Lenses With Flash Mirror Finish, With Super-Hydrophobic Front Coating And Anti-Fog Back Coating* Supplied With Moulded EVA Hard Case, Protective Lens Sleeve And Endura Embossed Soft Wipe Microfibre Carry PouchSpecifications:* 100% UV Protection
