Saint Laurent knows a thing or two about luxury eyewear, and these SL 610 sunglasses are definitely no exception. This exaggerated, squared silhouette is crafted from thick black acetate - while expansive tinted lenses provide protection in warm weather. And that’s not forgetting that all-important logo engraved onto the temples - the luxury seal of approval. 80% Recycled Acetate, 20% Bio Nylon Frames, Tinted Lenses, 100% UVA & UVB Protection, Engraved Branding, Made in Italy.
