Product description
Mirrored Single-Lens Running Sunglasses – FIANDRE
FIANDRE is DEMON’s new running eyewear model, designed for both road running and trail running.
Compared to the ROUBAIX model, FIANDRE stands out for its less angular, more streamlined lens shape, which gives a smoother, more elegant look and integrates better with the face without sacrificing the coverage and protection typical of mask-style sunglasses.
The mirrored, multilayer, single-piece lens makes FIANDRE ideal for runners on asphalt and dirt, where eye protection, lightness, and stability are essential.
High-contrast mirrored lens
FIANDRE’s lens is designed to provide high contrast and enhance natural colors, improving awareness of the surrounding environment.
This technology delivers benefits similar to a polarized lens, without compromising the visibility of LED screens such as smartwatches and other electronic training devices.
Visual protection remains effective even in very bright light and during prolonged use.
Available lens options
FIANDRE is available with different mirrored lens options, designed to adapt to varying light conditions:
Mirrored Smoke Lens
Featuring a dark tint, it is ideal for full-sun days. It reduces glare and ensures clear, relaxed vision even in intense light.
Sports use
Trail running
FIANDRE is an excellent trail-running sunglass, suitable for both beginners and experienced runners.
The mask-style lens effectively protects the eyes from leaves, branches, dust, insects, and debris typical of forest trails. Despite its wide coverage, the sunglasses weigh only 30 grams, ensuring comfort even on longer runs.
The category 3 mirrored DMIRROR lens provides high protection from sunlight and is shatterproof, offering maximum safety even in the event of strong impacts.
Road running
FIANDRE also performs exceptionally well for road running.
The streamlined lens shape protects the eyes from wind, dust, and insects, improving visual comfort while running. The lens ensures excellent performance in very bright conditions and during extended use, typical of the summer season.
The ultra-light and flexible frame, with hypoallergenic rubber inserts, guarantees a stable and comfortable fit. Once worn, FIANDRE becomes an essential companion for every runner.
Triathlon, marathon, and other disciplines
FIANDRE is recommended for all running disciplines.
It provides complete protection from intense light and accidental impacts, maintaining stability and comfort even in the most demanding conditions.
It is especially suitable for triathlon thanks to its lightness, durability, and fit, which help during transitions between swimming, cycling, and running. Also perfect for marathons, FIANDRE ensures continuous protection over the full distance, allowing the athlete to focus solely on performance.
Technical features and materials
FIANDRE’s DMIRROR multilayer lens is made from high-quality, shatter-resistant polycarbonate.
It provides effective UV protection and is designed to withstand even strong impacts without breaking.
In the event of impact, polycarbonate distributes energy across the entire lens surface, preventing the formation of dangerous fragments that could harm the eyes.
Every detail is engineered to ensure maximum safety and visual clarity.
Frame
FIANDRE’s frame is made of TR90, a special combination of carbon fiber and nylon.
Despite its substantial size, total weight is only 30 grams. The elastic structure adapts perfectly to the shape of the face, offering comfort without pressure and excellent stability while running.
All rubber parts, including the nose pads, are made of hypoallergenic Megol: a grip technology that prevents annoying micro-slips caused by sweat, vibration, or head movement.
FIANDRE is an ultra-light mirrored running sunglass, ideal for road running, trail running, marathons, and triathlon.
Compared to ROUBAIX, it features a softer, more streamlined, and less angular lens design, while maintaining the same protection, technology, and performance.
Thanks to innovative materials, FIANDRE is about 20% lighter than conventional materials, more resistant to impacts and tension, and built to last.
