Saint Laurent SL 572 vs SL 662: Which Naked Wirecore Frame is Right for You?
Both the Saint Laurent SL 572 and SL 662 belong to the brand's innovative Naked Wirecore collection, featuring the distinctive visible metal wirecore embedded in transparent acetate with laser-etched Saint Laurent logos. However, they offer different aesthetic approaches to this signature technology.
The SL 572 represents the boldest expression of the Naked Wirecore concept. With its squared, sharp shape and the largest corner angle Saint Laurent has ever produced (1cm), it's designed for maximum visual impact. The 50mm lens width and aggressive angles create a statement piece that works particularly well for those who want their eyewear to be a focal point of their look. Customer reviews consistently mention the "chunky" aesthetic and bold presence of these frames.
The SL 662, by contrast, offers a more classic rectangular interpretation of the wirecore technology. Described as the "mid evolution" of the Naked Wirecore concept, it features gentler angles and a slightly larger 57mm lens width. The SL 662 maintains the innovative wirecore construction and premium materials but in a more understated silhouette that may appeal to those seeking luxury eyewear with a subtler profile.
Price consideration: The SL 662 comes in at a lower price point ($230.77–$340.15) compared to the SL 572 ($362.11–$364.16), making it an attractive option if you want the Naked Wirecore technology at a more accessible price.
Our recommendation: Choose the SL 572 if you want the most distinctive, fashion-forward expression of Saint Laurent's design innovation—the kind of frame that turns heads and starts conversations. The dramatic corner angles and squared shape make these instantly recognizable. Opt for the SL 662 if you prefer a more versatile rectangular frame that still showcases the wirecore technology but with a more classic, wearable silhouette suitable for both casual and professional settings.
