Ideal for a day of fun in the sun, Costa's Isabela is a beautiful rendition of its namesake, Isabela Island in the Galapagos. Don't let the head-turning, designer look fool you, these sunglasses are just as functional as they are striking. Whether you're fishing, beach-combing, or voyaging into the great blue somewhere, Isabela is there with polarized lenses and a lightweight nylon frame to help you keep your eyes wide open. And as always, every pair of Costa sunglasses comes with a Costa Case, cleaning cloth, and manufacturer's Limited Lifetime Warranty.
