Technical Characteristics and Materials:
The robust MIRROR multi-coated lens of the GRAVEL model is made of impact-resistant polycarbonate. It offers excellent UV protection and superior safety against accidental impacts. The polycarbonate lens dampens shock across its surface with a "spider web" effect, preventing small fragments from forming and potentially damaging the eye.
Each lens element and component is designed to provide maximum protection and clear vision for the athlete.

The ultra-thin frame is made of TR90, a special blend of carbon fiber and nylon. Despite its size, the total weight of the GRAVEL sports glasses is only 30 grams. They are designed for athletes seeking products crafted from technical materials that provide optimal protection and safety. The frame is flexible, adapting to the shape of your face for a friction-free wearing experience and maximum stability.
The soft, non-slip nose pads conform to every nose shape. All rubber components, including the nose pads, are made of soft, hypoallergenic megol, ensuring maximum stability and preventing the glasses from sliding down your nose due to vibrations and head movements.
GRAVEL represents the best choice for those seeking sports eyeglasses with an ultra-light mirrored lens suitable for all sports. This material makes the GRAVEL DMIRROR multilayer single-lens glasses 20% lighter than traditional materials, while also being more resistant to accidental impacts and stress, and more durable over time.
