The SALT. Optics COLUMBIA 56 RX brings the iconic aviator shape to eyewear. This frame elevates the classic silhouette with a blend of style and function. A 1mm acetate insert reinforces the lens, enabling pairings of materials like titanium and glass that were previously incompatible. This insert also introduces color variation through bold contrasts and subtle monochrome tones. The organic SALT. pattern is custom-stamped on the temple tips and nose pads, adding a unique brand identity.
