STYLE & DESIGN INSPIRATION The name says it all. This frame commands respect. The serious shape exudes dignity and importance. The keyhole nose bridge connotes a certain substance and depth of personality. Gravitas gives you audacity. FRAME TECHNOLOGY The frame front is hand crafted out of premium Italian acetate from Mazzucchelli 1849. The temple arms are precision machined from aluminum to exacting detail and mounted with custom seven-barrel stainless steel hinges. The back half of the temple arms are hand crafted from Italian cellulose acetate from Mazzucchelli 1849 and have a wire core for adjustability in fit as well as inlaid temple pads for performance. LENS TECHNOLOGY Laser etched with the signature Z, the nylon lenses by Carl Zeiss are ultra-premium, impact resistant, and optically pure. They provide 100% UVA and UVB protection with precise clarity. Polarized, flash mirror and back side anti-reflective coating options are available with some colorways.
