The Costa Tuna Alley received its pro card with all new features that enhance your angling adventures and leisurely activities. The Tuna Alley Pro comes equipped with sweat management channels along the length of the temples for draining away moisture and sweat. In addition, the fish wont leave your sight with the built-in eyewire drains on the lenses which prevent water from building up inside the frame. If your fishing battles or outdoor activities become rigorous, the improved (more durable) Hydrolite rubber on the adjustable nose pads and temple tips provide optimum grip. These new Costa sunglasses are available in prescription.
