SPEED VENT is the latest eyewear model from DEMON. Designed for road running and trail running, these glasses feature a multi-layer mirrored lens that provides maximum eye protection and an aggressive design.

Types of Sports:
Trail Running: SPEED VENT is an excellent choice for trail running, suitable for everyone from amateurs to professionals. The wide frame provides maximum protection in forested areas against leaves, branches, dirt, insects, and other potential hazards. Despite the large frame, the glasses weigh only 30 grams. The DMIRROR multi-layer lens, rated category 3 for darkness, effectively protects against intense light, even during prolonged use. The lens is unbreakable, ensuring safety during strong impacts. Additionally, the glasses feature adjustable nose pads and non-slip rubberized components for maximum stability during jumps and vibrations.
Road Running: SPEED VENT is ideal for road running. The wide design offers excellent protection for the athlete's eyes from air, dust, insects, and other dangers. The lens adapts to provide protection in bright light conditions and during prolonged use, typical of summer. The glasses are comfortable, with an ultra-light and elastic frame, hypoallergenic rubberized parts, and an adjustable nose pad. Once you try them, you won't want to be without them.
Walking, Cross Country, and Other Disciplines: SPEED VENT is recommended for all running disciplines. These glasses provide maximum eye protection from light and accidental impacts, ensuring stability and comfort. They are perfect for those seeking lightweight, protective running eyewear with an aggressive aesthetic.

Technical Characteristics and Materials:
The DMIRROR multi-layer lens of the SPEED VENT model is made from solid, high-quality, impact-resistant polycarbonate. It effectively protects the athlete's eyes from UV rays and accidental impacts, even strong ones, without breaking. In the event of an accident, the polycarbonate lens disperses shock across its surface with a "spider web" effect, preventing the formation of small fragments that could damage the eye. Every detail and material used in the lens composition ensures maximum safety and an optimal fit for the athlete's eyes.
The ultra-light frame is constructed from TR90, a specialized composition of carbon fiber and nylon. Despite the size of the frame, the overall weight of the SPEED VENT running glasses is only 30 grams. Designed for athletes, these glasses are built with technical materials that guarantee maximum protection and safety. The elastic frame adapts to the shape of the head for maximum comfort and stability.
The adjustable nose pads conform to every nose shape. All rubberized components, including the nose pads, are made from soft hypoallergenic Megol, utilizing grip technology that ensures maximum stability and prevents the glasses from sliding down the nose due to vibrations and head movements.

SPEED VENT is a must-have for those seeking ultralight running glasses with mirrored lenses for road and trail running on dirt roads and in mountainous terrain. This design makes the DMIRROR multi-layer single-lens running glasses 20% lighter than conventional materials, while also being more resistant to accidental impacts and stress, and more durable over time.
