FIANDRE Photochromic Running Sunglasses for Road & Trail Running
FIANDRE is the new running sunglasses model by DEMON, designed for road running and trail running.
Compared to the ROUBAIX model, FIANDRE stands out for its less angular and more streamlined lens shape, delivering a more fluid and elegant look while maintaining the same technical performance and protection typical of shield-style sunglasses.
Equipped with mirrored DCHROM® photochromic lenses, FIANDRE is designed for runners looking for high performance, lightness, and versatility suitable for all light and weather conditions, in every season of the year.
The latest-generation photochromic lenses automatically adapt to changes in light, darkening and becoming mirrored when needed to always ensure clear and comfortable vision.
Photochromic Lens for All Light Conditions
A distinctive feature of FIANDRE lenses is their slightly tinted base color, which allows the sunglasses to be used even in low-light conditions such as early morning runs, dusk, or overcast skies. In these situations, the lens provides effective protection from the elements without compromising visibility.
Trail Running Sunglasses with Blue Mirrored Photochromic Lens – FIANDRE Model
As shown in the images, FIANDRE’s lens proves extremely versatile and suitable for any lighting condition. It is particularly effective in critical low-light situations, such as bad weather or sunset, while still delivering high performance under intense sunlight.
Sports Applications
Trail Running
FIANDRE is the ideal eyewear for trail running, suitable for a wide range of runners from beginners to experienced athletes.
The shield-style frame ensures complete eye protection in natural environments, defending against branches, leaves, dirt, insects, and debris encountered on trails. Despite its wide coverage, the sunglasses weigh only 30 grams, ensuring comfort even during long outings.
The latest-generation mirrored DCHROM® lens features a slightly tinted base color and reaches Category 3 under maximum sun exposure. It dynamically adapts to changes in trail lighting, lightening and darkening naturally. The lens is also shatterproof, providing high impact resistance and maximum safety during activity.
Road Running
FIANDRE also proves to be an excellent companion for road running, both for short and long distances.
The streamlined lens shape offers complete protection from wind, dust, and insects, improving visual comfort while running. The photochromic lens reacts quickly to brightness changes typical of urban and suburban environments, making FIANDRE ideal for summer conditions and prolonged use.
The ultra-lightweight and flexible frame, with hypoallergenic rubber inserts, ensures a stable and comfortable fit. Once worn, the sensation of protection and lightness makes FIANDRE hard to give up.
Cross-Country, Track, Triathlon & Other Disciplines
FIANDRE is recommended for all types of running. It offers full protection from external elements, stability during movement, and high comfort even under intense use. It is the ideal choice for runners looking for lightweight, technical sunglasses with a modern and harmonious design.
Technical Features & Materials
DCHROM® photochromic lenses represent advanced technology in sports optics. When exposed to UV rays or sunlight, they activate a reversible chemical reaction that causes the lens to darken; as light intensity decreases, they gradually return to their original clear state.
Made from high-quality polycarbonate, they offer:
- Significant weight reduction
- High impact safety, with no fragments
- Total UV protection
DCHROM® lenses start from a slightly tinted base color and reach Category 3, ensuring excellent visual comfort even on very sunny days and during prolonged use.
Frame
The FIANDRE frame is made from TR90, a special combination of carbon fiber and nylon.
Despite its solid appearance, the sunglasses weigh only 30 grams. The flexible structure adapts perfectly to the shape of the face, offering pressure-free comfort and excellent stability while running.
FIANDRE is the ideal choice for runners seeking ultra-lightweight mirrored photochromic running and trail running sunglasses, featuring a more streamlined and less angular design than ROUBAIX, capable of combining aesthetics, protection, and advanced technology across all running disciplines.
