Flaunt a sporty style wearing the Antarctica sunglasses. ECONYL® regenerated nylon (from fishing nets from Patagonia and other discarded nylon) in the frames is hypoallergenic, durable, and lightweight. Nose pads and temple tips ensure the glasses won't slip off. Rectangular rounded rims flatter round, square, oval, and heart-shaped faces. These full rim sunglasses sport the Karün logo on the temples for a signature look.
