Dive deep into sophisticated style with a pair of Costa Mariana Trench 200 eyeglasses. Costa crafts these frames in lustrous acetate, a material prized for its light weight, hypoallergenic properties, flexibility, and durability—for comfort you can depend on through years of wear. The skull temples curve gently behind the ears to keep the glasses securely in place. A keyhole bridge provides a roomy fit that balances the weight of the frames to keep them comfortable no matter where your adventures take you.
