Tetra is a signature RSF frame: a chunky, oversized silhouette with a distinct street edge. With thick rims and wide oval lenses, Tetra balances timeless classicism with modern, sharp features. Inspired by 1990s references, Tetra captures the perfect blend of understated elegance and raw edginess for an effortless everyday style. This version features a crystal ochre acetate and bright orange lenses.
