Which Costa Should You Buy?

Costa's frames in the grid share a lens story. The 580G is a glass lens that is scratch-resistant and optically clear but heavier. The 580P is polycarbonate, lighter and more impact-resistant. Both are polarized to cut glare off the surface, which makes it easier to see fish, boat wakes and channel markers.

Lens color matters: blue mirror suits open water, while copper or green lens colors help in shallow, inshore fishing. Frame width is listed in millimeters, so match it to a pair you already own. Glass lenses suit people who value clarity, while polycarbonate suits anyone who is hard on their gear.

Costa frames come in several sizes, so a XL Paunch will look different from a mid-width Sullivan. Check the millimeter measurement before you order.

Care matters too. Rinse saltwater off the lenses with fresh water and use the supplied cloth, since dry-wiping salt crystals can scratch even a tough coating.

When Do Costa Deals Drop?

Black Friday is November 27, Cyber Monday is November 30, and Amazon still has to say when its own Black Friday Week starts. The company's Black Friday FAQ confirms those two dates and says early deals are live in its Holiday Shop now.

Sunglasses are also a seasonal buy, so winter can be the cheaper time to shop for next summer. We pull live Amazon pricing daily. If you want to see more frames, our Black Friday sunglasses deals covers other brands.
