Saint Laurent SL 660 vs. Similar Rectangle Frames
If you're drawn to the Saint Laurent SL 660's bold rectangle shape and contemporary design, you might also consider these alternatives from the same collection:
SL 660 vs. SL 572
The Saint Laurent SL 572 shares the wirecore design concept and rectangle shape, with a nearly identical price point ($361-$364). Both frames offer the same unisex styling and prescription-ready construction. However, the SL 660 stands out with its signature 1cm corner angles—the largest Saint Laurent has ever produced—and its more pronounced Naked Wirecore aesthetic. The SL 660 has also gained more celebrity visibility, being worn by Druski, Gunna, and several athletes. If you want the most architecturally distinctive frame with maximum visual impact, the SL 660 is the stronger choice.
SL 660 vs. SL 658
The Saint Laurent SL 658 offers a bold rectangular design at a more accessible price ($297.79), making it an attractive option if you're budget-conscious. Both frames are prescription-ready and feature contemporary Saint Laurent styling. The key difference is the SL 660's innovative Naked Wirecore construction—the visible metal core running through the temples and the laser-engraved logo in super-shiny finish. The SL 660 also features recycled acetate and bio nylon lenses, reflecting a more sustainable approach. If the technical, industrial aesthetic and distinctive wirecore detail are important to you, the SL 660 justifies the higher investment.
Our recommendation: Choose the SL 660 if you want Saint Laurent's most architecturally innovative rectangle frame with celebrity-approved style and the distinctive Naked Wirecore feature. It's the statement piece in the lineup.
