Costa achieves a cool, sporty style in the casual C-Mates Bifocal Readers Whitetip sunglasses. These full-rim rectangular frames are made from bio-based nylon, a durable, flexible, material that resists heat and cold. Rims are vented in the front for airflow to keep you cool and reduce fogging. The temples curve inward and feature gripper holes at the tips for a secure fit, with the Costa logo at the temple end for a stylish pop. Enjoy a relaxed feel with a modern look when you step out wearing these Whitetip sunglasses from Costa.
