From Alba:

The iconic DELTA family is expanding, including new frames in a chic glossy finish. Now available with the brilliant VZUM™ LEI lens, adapted to the shapes and sizes of a smaller facial structure. Lighter glasses with a tailored fit, that maintain the same performance characteristics such as internal ventilation, visual coverage and eye protection. The material of the frames is Tr90, made from nylon and carbon fiber, organically compatible and safe to the skin, even after a prolonged use. It is 20% lighter that other conventional materials and it offers more protection against crashes and tractions. It provides a high resilience without deformation when exposed to high temperatures. The glasses wearability allows a perfect vision when shifting your eyes from the pedals to the road. This particular aspect enables the athlete to stay focused on his performance without interferences. The temples are strong and guarantee to stay put even in case of shocks or sudden head movements.
