Design story

Sunwear, with stronger character.

Mercer is defined by its retro statement silhouette, built to feel visually distinctive while remaining naturally wearable. The frame keeps its original New York-inspired personality, but reads more elevated in a sunwear context.

Crafted with bold bio-acetate temples and retro front, it brings together design character, everyday comfort and a confident silhouette that moves easily between city wear, travel and long summer days.
