So Costa Blackfin or Costa Tuna Alley?

Each frame has distinctive features that could sway the decision one way or another. The Blackfin features Hydrolite, Costa's patented rubberized material, on its nose pads and all along the cheeks and temples. Instead, the Costa Tuna Alley has vents on the face of its frame with Hydrolite along the vents' back. Both Hydrolite and vents are incorporated to manage perspiration. As sweat builds up the Hydrolite becomes tacky, preventing slippage. The venting system allows additional airflow to cool the face. Expect both features to keep the frames in place.

With similar dimensions, the Tuna Alley has slightly taller lens and wider frame, the choice boils down to styles. For a more aggressive look, pick Costa Tuna Alley. The vents and sharper curves evoke the fisherman's spirit. Leave the Tuna Alley on the boat and sport the Blackfin for a more inviting set of frames.
