The Costa Blackfin PRO takes one of Costa's most popular frames and elevates it. We've kept the original's iconic look, polarized lenses, and trusted fit, then added six angler-approved enhancements to keep you on the water longer and more comfortably. Enjoy crystal-clear vision thanks to a new vented and fully-adjustable nose pad for a custom fit, along with integrated sweat channels and eyewire drains. Plus, side shields, hooding, stickier HydroliteA(R), and metal keeper slots work together to ensure your frames stay secure and your focus remains locked on the fish.
