Estero Aviator Sunglasses combine a bold square silhouette with modern aviator design. Crafted from bio-based resin and steel, they offer lightweight durability and a snag-free fit. A double bridge, sculpted nose pads, and aviation-inspired details define their distinctive character. Large, square, polarized CR-39 amber lenses provide superior clarity, UVA+UVB protection, and confident coverage for all-day wear.
