The Corsair — Polarized Square Sunglasses

A flat-top square in full-rim acetate. Squared enough to read as deliberate, restrained enough to wear every day. The brow sits level across the face, the rim carries real thickness, and the whole frame is cut and hand-polished from sheet acetate rather than injection-molded from plastic pellets — which is why it feels dense in the hand and settles instead of sliding.

Dimensions

• Lens width: 55 mm (2.2 in)
• Bridge width: 18 mm (0.7 in)
• Temple length: 150 mm (5.9 in)

The widest frame in the range — a true large fit.

Key Features

• Polarized Lenses — Cut glare off water, snow, and pavement for sharper, lower-strain vision
• UV400 — 100% UVA/UVB Protection — Full-spectrum block to 400nm
• Hand-Polished Acetate Frame — Cut from sheet acetate, tumbled and polished by hand for depth of color and a warm, substantial feel
• 5-Barrel Metal Hinges — Five interlocking barrels cored directly into the acetate for a firm, repeatable open that holds its tension
• Unisex Fit — Four colorways: Black/Green, Tortoise Shell, Crystal, and Navy
• Complete Kit Included — Branded folding case, matching pouch, and cleaning cloth in every order

Care

Rinse with cool water and dry with the included cloth. Avoid alcohol, ammonia, and household cleaners on the lenses. Do not leave in a hot car or on a dashboard — sustained heat can warp acetate. Store in the case when not in use.
