Designed in collaboration with the cult British brand A Cold Wall, this model is a cutting-edge interpretation of brutalist design aesthetics. Based on RSF's signature Caro silhouette, the model's geometric features were thickened for a sharp, angular design. This version features a marbled acetate with tinted blue lenses.
