Three outstanding innovations were applied to the key points of the frames, the temples and the lenses. An exclusive pure titanium hinge was developed by Grosfilley, for the ZILLI collection, representing the famous ZILLI ingot. The lingot ZILLI, is also present on the outer part of the branches, with contrasts, due to the different titane treatments (gold, paladium or ruthenium).

Developed in collaboration with our Italian partner DIVEL, especially for ZILLI, equipped with the latest anti-reflective technologies, anti-scratch and anti-fouling treatments (oleophobic), our polarized sun lenses guarantee a clear vision with contrasts and color fidelity.
