Introducing the Saint Laurent SL 364 Mask Ace sunglasses, a refined expression of Italian luxury. Crafted in Italy, these sunglasses present a deep black finish with a rectangle-to-square silhouette that speaks to modern elegance. The lens width measures 99 mm and the lens height 51 mm, complemented by a slender 1 mm bridge and 145 mm temples for a balanced, comfortable profile across longer wear sessions.

In a pure black palette, the frame channels Saint Laurent’s timeless sophistication. The Rectangle sunglasses styling lends structure to a variety of looks, from tailored business ensembles to chic weekend outfits, while remaining distinctly premium and contemporary. The frame’s clean lines are designed to translate seamlessly from desk to dinner.

Designed for comfort, the design prioritises a secure, flattering fit: a temple length of 145 mm and a compact bridge of 1 mm work together to deliver a balanced, all-day feel. The frame’s contouring and finish are crafted to accommodate prescription lenses when required, offering flexibility without compromising style.

As part of Ardor Eyewear, you can buy the frame alone or with prescription lenses. Our service includes prescription-ready customization, and we deliver authentic packaging with guaranteed provenance in 8–12 days for your enhanced eyewear.

Face-shape guidance: the Rectangle sunglasses silhouette tends to suit oval and round faces best, while also flattering oblong or long faces. This Saint Laurent pair is ideal for urban professionals who value luxury and effortless style, pairing seamlessly with a modern, aspirational lifestyle.
