Designed for the demanding adult cyclist and mountain biker who faces constantly changing light conditions, these glasses offer uncompromising performance, protection, and style. Move seamlessly from bright, open-sky sections to dark, tree-covered singletrack without ever needing to stop or swap your eyewear. The full-frame styling provides maximum coverage, ensuring your eyes are shielded from debris, wind, and harmful rays while you focus on the path ahead.The heart of these high-performance sunglasses is the advanced light-reactive main lens. Featuring cutting-edge Photochromic technology, the lens automatically adjusts its tint to match the ambient light levels, transitioning smoothly across the Photochromic 1-3 range. This means you get the perfect amount of shading in bright sun and enhanced clarity in lower light, all in a single lens. The high-definition, one-piece cylindrical profile provides an expansive, unobstructed field of view, boosting your peripheral vision and depth perception so you can spot every root, rock, and obstacle with precision.Engineered for the rigors of the ride, the lightweight and durable synthetic TR90 frame delivers all-day comfort. Custom temples with injection-moulded rubber tips ensure a secure, slip-free fit that stays put even on the roughest descents and sweatiest climbs. Never let the weather dictate your ride again, the main lens is treated with a super-hydrophobic front coating that causes water and spray to bead off instantly, while an anti-fog back coating prevents condensation build-up, maintaining clear vision in all conditions. For ultimate versatility, an additional amber lens for extremely low-light situations is also included. These sunglasses provide 100% UV protection, safeguarding your eyes during long days on the saddle.Attributes: Adult, Photochromic, Photochromic 1-3, Synthetic Technical SpecificationsSingleTrack eyewear featuring full-frame styling, inter-changeable cylindrical lenses.Features:* Lightweight TR90 frame and custom temples with injection-moulded rubber tips* One-piece cylindrical profile, high-definition, light-reactive polycarbonate main lens with fLash mirror finish with super-hydrophobic front coating and anti-fog back coating* Additional amber (low light) lens included* Supplied with Endura moulded EVA hard case, protective lens sleeve and embossed soft wipe microfibre carry pouch* Replaceable arms in case of accidental damage (not included)* 100% UV Protection in compliance with EN ISO 12312-1:2013
