1. Much longer time Antifog performance 180sec(Please find the test report below).

2. The material we use is chemical resistant, which is especially suit for the helmet visor, as the conventional technology is not with chemical resistance.

3. Unlike most photochromic/Antifog standard lenses, lenses are firmly injected in the mass of the polymer itself with a advanced manufacturing process, making it more resistant and clearly optically superior to most competitors.
