Costa Finlet Polarized Performance Sunglasses – 8-Base Wrap Frame with Side Shields, Hydrolite® Grip & 100% UV Protection

Built to conquer harsh conditions and long days under the sun, the Costa Finlet sunglasses are a go-to for anglers, boaters, and outdoor enthusiasts who demand high-performance eye protection. Named after the small, stabilizing fins found on fish, the Finlet's sleek side shields offer extra coverage against wind, glare, and debris—making it an ideal companion for water and offshore adventures.

Featuring a rugged 8-base wrap design, the Finlet provides maximum field-of-vision coverage and a secure fit. Double-injected Hydrolite rubber nose pads and temples ensure the glasses stay locked in place—even during sweaty pursuits. Retainer-ready temple tips let you attach your favorite leash system for added peace of mind when you’re pushing limits.

With Costa’s industry-leading 580 polarized lens technology, these sunglasses cut through surface glare, boost contrast, and block 100% of harmful UV rays, so you can stay focused, sharp, and protected, no matter how long you’re out there.
