Tonneau in Obsidian sunglasses exude heavyweight structure with minimal fuss. The squared silhouette, in deep black acetate, achieves brutalist geometry with refined edgework. Polarized lenses offer 100% UVA/UVB protection in smoke grey for neutral sun coverage. A sculpted saddle bridge ensures comfort, while five-barrel metal hinges add stability and strength. The high-gloss, hand-polished surface completes these bold, sculptural frames.
