Tortoise with Blue Mirror Lens
Fantail
Great Fit & Amazing Comfort
These co-molded frames are a bit smaller, but definitely akin to the classic styling of the Blackfin frames. Adventure-ready? You bet.
Costa's co-injected bio-based nylon frame material is both tough and durable, while offering a comfortable fit. TR-90 nylon is a premier material for sports and performance frames as it is resistant to heat and cold. Though it is flexible, it is still durable. Nylon is easily molded into Costa's iconic wraparound shape.

580G - Lightwave GlassCosta's most high tech lens - glass provides the most superior clarity. Costa's encapsulated mirrors (between layers of the glass) are scratch-proof. Costa's glass lens is 20% thinner and 22% lighter than the industry's average polarized glass lens while still blocking 99.9% of glare. |
580P – PolycarbonatePolycarbonate is the lightest and most durable lens material option. Providing high clarity, impact resistance and light weight all day wear-ability. The C-Wall molecular bonded mirrors provide the most scratch-resistant and smudge-free barrier, repelling water, oil, and sweat for easier cleaning. |
PolarizationPolarized lenses are essential for anyone who spends time outdoors - especially on the water. But, not all polarized sunglasses are created equal. Costa is 99.9% polarized, providing the best efficiency available so that reflective glare is blocked-reducing eye strain and headaches. |
MirroredCosta's mirrors are more than an aesthetic and a necessity in harsh sunlight. Made through a high-tech ion beam deposition process, these multilayered thin film coatings make for the most scratch-resistant mirrors out there. |
