Running Glasses for Road Racing and Trail Running: Photochromic ROUBAIX
ROUBAIX represents the ideal choice for road and trail running, featuring mirrored photochromic lenses—an innovative advancement from DEMON. This model is specifically designed for runners seeking a combination of photochromic functionality and an attractive aesthetic. Suitable for both road and trail running, ROUBAIX delivers optimal performance in various light and atmospheric conditions throughout the year. The latest-generation photochromic lenses automatically adapt, darkening and mirroring light changes to ensure a clear, sharp, and comfortable view.
A unique feature of these lenses is their slightly sheer initial tint, which allows athletes to use ROUBAIX effectively in low-light conditions or at dusk, providing essential protection against atmospheric elements for the eyes.

As shown in the photo, the lens is suitable for bright conditions, particularly in critical low-light situations, such as during bad weather or at sunset. However, it is equally effective in bright conditions.
Types of Sports:
Trail Running: ROUBAIX is the ideal choice for trail running, accommodating a wide range of users from beginners to professionals. The wide frame offers optimal protection for runners in wooded areas, shielding the eyes from leaves, branches, dirt, insects, and other debris. Despite their size, the glasses weigh only 30 grams, ensuring comfort during use. The advanced DCHROM® mirrored lens features a slightly sheer base color and reaches category 3 performance, taking on a purplish-red hue in bright conditions. It dynamically adapts to changes in brightness along the trail, lightening and darkening as needed. Additionally, the lens is shatterproof, guaranteeing exceptional resistance to impacts without the risk of breakage, ensuring maximum safety during activities.
Road Running: ROUBAIX is also exceptional for road running, whether for short or long distances. Its wide design offers complete protection from air, dust, insects, and other potential hazards. The standout feature of the lenses is their ability to adapt to variations in light, darkening or lightening as necessary. These lenses are particularly recommended for intense brightness conditions typical of summer and for prolonged use. The glasses provide optimal comfort thanks to their ultra-light and elastic frame, equipped with hypoallergenic rubberized components. Once you experience their performance, you won't want to be without them.
Cross Country, Track Running, Triathlon, and Other Disciplines: ROUBAIX is suitable for any type of running, offering maximum protection from external elements and accidental impacts while ensuring stability and comfort during activities. Its essential features meet the needs of those seeking lightweight running glasses with aggressive aesthetics and optimal eye protection.

Regardless of the discipline, ROUBAIX combines the versatility of photochromic lenses with the aesthetics of a mirrored lens, offering athletes eyewear with a strong visual impact alongside advanced photochromic technology.
IMPORTANT NOTE: The mirrored color does not affect your external vision, as the lens is internally smoke-colored.
Technical Characteristics and Materials:
The new DCHROM® photochromic lenses represent a significant innovation in optics. They react to UV radiation or sunlight, initiating a reversible chemical reaction that causes them to darken. Once the light exposure ends, the lenses gradually return to their original transparency. Made from high-quality polycarbonate, these lenses offer numerous technical advantages. First, polycarbonate significantly reduces lens weight compared to conventional materials. Furthermore, it ensures safety in the event of an impact, as it does not produce fragments that could damage the eyes. These high-tech filters provide effective protection against UV rays, ensuring both safety and comfort.
The DCHROM® lenses mark an evolution in photochromic technology. Starting from a light veiled color, they reach category 3 during maximum exposure. In addition to the rapid transition from light to dark, these lenses provide remarkable comfort to the eyes, even on days with intense sunlight and during prolonged use.
The frame of ROUBAIX, made from TR90—a special composition of carbon fiber and nylon—is extremely lightweight. Despite its size, the ROUBAIX glasses weigh only 30 grams in total. This model is designed for athletes who require products made from technical materials that ensure maximum protection and safety during activities.
The frame is elastic and adapts perfectly to the shape of the head, ensuring optimal comfort without being overly tight. At the same time, it offers exceptional stability during use.
ROUBAIX is an essential choice for those seeking ultra-light mirrored photochromic running glasses suitable for any running discipline. Made from innovative materials, these glasses with DCHROM® photochromic mirrored lenses are 20% lighter than conventional materials, providing greater resistance to accidental impacts and stresses while ensuring enhanced durability over time.
