PUSH IT TO THE LIMIT WITH COSTA DEL MAR
Built by hand and backed for life, these Costa sunglasses are the only pair you'll ever need. You might have gallons of brine in your face and 600 pounds on the hook, but these sunglasses still won't slip. The Hydrolite™ injected lining takes care of slip resistance and the flexible frames mean serious comfort. The Blackfin sunglasses push the edge in sunglass performance so you can push it everywhere else.
