Photochromic Running Sunglasses for Road Running, Trail Running and Triathlon – LIEGI

LIEGI is the new DEMON sports sunglasses model designed for runners and triathletes who want protection, lightness, and maximum versatility in every condition of use.

Designed to support you during road running, trail running, and triathlon, LIEGI combines a modern, dynamic design with advanced technical solutions, offering a stable fit, high protection from external elements, and consistently sharp vision. The DCHROM® mirrored photochromic lenses, adjustable nose pad, and adjustable temples make this model especially versatile and suitable for different face shapes, ensuring comfort and a precise fit even during the most intense activities.

Perfect vision in every light condition

LIEGI features DCHROM® Category 1–3 mirrored photochromic lenses, designed to automatically adapt to changes in brightness. In stronger sunlight, the lens gradually darkens, while in lower-light conditions it becomes clearer again, always maintaining an excellent balance between protection and visual comfort.

This feature makes LIEGI ideal for training sessions and races in every season, from early morning outings to sunset routes, as well as variable days with sun, clouds, wind, or bad weather. The lens ensures comfortable, responsive vision, helping the eyes adapt quickly to the environmental changes typical of outdoor running.

DCHROM® photochromic lens: protection, comfort and performance

DCHROM® lenses represent an advanced solution in sports optics. Thanks to their photochromic technology, they react to light and UV rays by changing tint naturally and progressively. The result is an extremely functional lens, capable of supporting the athlete in very different contexts without the need to change eyewear.

UV400 protection ensures maximum shielding against UV-A and UV-B rays, effectively protecting the eyes during prolonged sports activity. The mirrored finish, in addition to enhancing the model’s aesthetics, also helps improve comfort in bright-light conditions.

Stability and customized fit

One of LIEGI’s strengths is its ability to provide a customizable and secure fit. The adjustable nose pad allows the support on the face to be fine-tuned, while the adjustable temples make it possible to further refine the fit according to individual needs.

This dual adjustment is especially useful during running and triathlon, where stability and comfort are essential. The sunglasses stay firmly in place even during the most dynamic movements, technical descents, pace changes, and heavy sweating, minimizing shifting and discomfort.

Ideal for road running

For road running, LIEGI provides effective protection against wind, dust, insects, and glare, significantly improving visual comfort during both daily training and long-distance races.

The lightweight frame and the fast-adapting photochromic lens also make it perfect for urban and extra-urban routes, where light conditions can change frequently between open stretches, shaded areas, tree-lined sections, and sudden weather changes.

Perfect for trail running

In trail running, LIEGI fully expresses its technical nature. The lens coverage protects the eyes from branches, leaves, dust, mud, small debris, and insects, while also offering a wide and comfortable field of vision.

The lightweight yet durable frame, combined with the adjustable nose pad and temples, ensures a precise fit even on the most demanding terrain. It is the ideal eyewear for those seeking reliability on climbs, stability on descents, and lasting comfort during long and technical outings.

Also excellent for triathlon

LIEGI is also an excellent choice for triathlon, where every detail matters. The versatility of the photochromic lens allows athletes to handle changing light conditions without interruption, while the ultra-light structure helps maintain comfort and focus even for many hours.

The adjustable fit is a real advantage during transitions and the most intense phases of performance, when you need eyewear that is stable, quick to put on, and capable of providing immediate protection.

Technical materials and ultra-lightweight design

The LIEGI frame is made of TR90 Ultralight, a technical material appreciated for its exceptional combination of lightness, flexibility, and strength. This allows the sunglasses to adapt naturally to the face, providing a feeling of prolonged comfort even during intense training or extended use.

Weighing just 28 grams, LIEGI feels extremely lightweight once worn, helping reduce fatigue and improving the sensation of stability and freedom of movement.

Sporty, modern and unisex design

LIEGI is designed with a clean, contemporary sporty style, created for those looking for technical eyewear that is also aesthetically refined. Its unisex fit, suitable for both men and women, makes it a versatile solution for a wide range of athletes.

The design is intended to integrate perfectly with performance: every detail is aimed at ensuring protection, lightness, ergonomics, and a bold look, suitable for both training and racing.
