Slate is built around a simple standard: exact materials, quiet design, and one honest price. Every frame comes with polarized lenses and 5-Point Flex hinges; every build combines Studio Acetate and stainless steel, with the exact construction listed on its product page.
Build Standard
The material standard does not change by shape, finish, or promotion. Choose the frame you want; the build stays consistent.
Polished acetate with deep color — in every build, from full-acetate frames to acetate-and-steel hybrids.
Polarized polycarbonate with AR back coat, hydrophobic, and oleophobic layers.
Spring-loaded 5-barrel stainless steel hardware for smoother daily wear.
One standard on every pair. No upgrade maze.
Material System
Frame, lens, and hinge are separate standards, so each gets its own close-up: acetate depth, coated lens performance, then hinge construction.
Studio Acetate is Slate's frame acetate — durable, flexible, hypoallergenic, with color depth that can be polished instead of painted over. Some frames are full acetate; others pair an acetate front or brow bar with stainless steel temples. Every product page lists the exact build.
Deep polished color⋅Durable, flexible, hypoallergenic
SlateShield is the coated lens system: polarized polycarbonate for lighter, impact-resistant wear, an anti-reflective back coat to reduce bounce-back glare, plus hydrophobic and oleophobic layers that help shed water and fingerprints.
Polarized polycarbonate⋅AR, water, and fingerprint resistance
The hinge is where quiet design becomes mechanical confidence: spring-loaded flex, stainless steel hardware, and a smoother open-close feel that supports daily wear.

You should not have to decode a spec sheet or wait for an upgrade prompt. Slate keeps the material floor visible.

Designed for close inspection
Slate does not rely on loud logos or trend churn. The frame has to make its case up close: acetate depth, hinge action, lens clarity, and a finish that feels intentional in hand.
Care
Better materials do not need complicated maintenance. They need a simple rhythm: rinse grit away, clean with microfiber, and store the frame when it is not being worn.
