Costa took one of their most beloved frames and made it even better. The Blackfin Pro builds off the original look, fit and polarization, but includes six new angler-approved additions to keep you fishing and on the water even longer: Vented and fully-adjustable nose pad for a custom fit, sweat channels and eyewire drains will help keep your vision clear, while side shields, hooding, new stickier Hydrolite® and metal keeper slots help you focus on fishing with less distractions.
