LOGAN Eyeglasses by Gotti. Color: Black matte, Dark Brown, Moss Green, Winered, Gold Brushed, Silver Brushed, Size: 50-19, Material: Titanium, Collection: Gtti Switzerland.. The Gotti Logan is a refined take on the retro cat-eye shape: rounded edges, a calm browline, and a measured uplift at the outer corners. Crafted from premium block titanium in Japan, this frame feels incredibly light. Titanium has an amazing strength-to-weight ratio that makes these frames comfortable for all-day wear. Choose from sophisticated colors to match your style. In matte shades like black or dark brown, the Logan feels graphic and minimal; in brushed gold or silver, the silhouette takes on a subtle radiance; moss green and wine red add depth.
