The JS Atlantic Tortoise brings a modern element to an American classic. Polarized Green lenses provide a subtle contrast to the gold and tortoise frame, creating a sleek combination. The frames are crafted from nickel-free stainless steel and high-grade Italian cellulose acetate. Each frame is individually hand-polished and assembled. Soft silicone nose pads are used for extra comfort and are attached to malleable nose pad wires to easily adjust fit. Our lenses are made from an impact-resistant CR-39 that provides incredible durability and exceptional visual clarity. Polarized lenses come standard, and all lenses include optimal protection by blocking 100% of UVA and UVB rays.
