Additional Information: Costa Lens Colors and Materials
For comfort and clarity, slip on a pair of Costa Blackfin sunglasses. Hydrolite rubber on the temples and nose pads prevents the shades from slipping. Full-rim frames consisting of bio-based TR-90 nylon are hypoallergenic, lightweight, flexible and sturdy for long-lasting use. With rounded edges on rectangular rims, the sunglasses complement round, square, oval, and heart-shaped faces. Skull temples provide a secure fit, while the saddle bridge disperses the weight evenly across your nose for comfort. These performance sunglasses for men will keep their form over years of water activities.
