Demon Fiandre Category 3 represents an evolution of the outdoor DEMON collection, designed for those seeking high protection, comfort, and a more fluid and elegant style.
These are sunglasses with a single mirrored and multilayer lens, designed to provide total eye protection during mountain and outdoor activities. The lens delivers rich and natural colors, high visual sharpness, and full readability of LED screens and digital devices.
In hiking, FIANDRE is suitable for both casual enthusiasts and experienced guides. The wide mask-style frame effectively protects against branches, leaves, insects, dust, and debris typical of forest trails. Despite the generous size, the weight is only 30 grams, a feature that contributes to comfort even after many hours of use. The category 3 DMIRROR mirrored lens protects against intense light even with prolonged exposure and is completely shatterproof, ensuring safety in case of impact.
In mountaineering, FIANDRE offers complete protection from wind, snow, and reflected light. The more streamlined design enhances aerodynamics and visual comfort, while the wraparound structure effectively shields against external elements and turbulence. The category 3 DMIRROR lens guarantees high performance even at altitude, resists strong impacts, and maintains reliability in every situation.
For ski mountaineering, the mask shape ensures protection from wind, snow, and dust, while the mirrored lens allows for clear and protected vision even on glaciers and in extreme brightness conditions. Comfort is enhanced by the ultralight and flexible frame and hypoallergenic rubber inserts that ensure stability during descents and dynamic phases.
The multilayer DMIRROR lens is made of high-quality polycarbonate, resistant to impacts and shocks. In case of a hit, it distributes the energy across the entire surface creating a "spider web" effect that prevents the dispersion of dangerous fragments, offering total UV protection and maximum safety for the eyes. The frame is made of TR90, a combination of carbon fiber and nylon that makes the glasses lightweight, flexible, and durable, adapting to the shape of the face without creating pressure points. The nose pads and all parts in contact with the skin are made of soft, hypoallergenic Megol, equipped with anti-slip technology that limits the movement of the glasses even in the presence of sweat, vibrations, and intense movements.
