No permit required to wear Costa's Permit sunglasses, even though they feel professional-grade enough to require a license. When staying put and staying comfortable matter most, every angler needs what has been described as an "extension of any hardcore fisherman's face". Hydrolite® lining, flexible hinges, and side vents, all come together to help you keep your eye on the prize because that trophy isn't going to catch itself. And as always, every pair of Costa sunglasses comes with a Costa Case, cleaning cloth, and manufacturer's Limited Lifetime Warranty.
