The Costa Rincon II is an upgraded version of Costa’s popular Rincon frame, designed for added coverage and performance on the water. It features micro side shields and frame hooding to reduce light leakage, vented nose pads to help minimize fogging, and double-injected rubber for improved grip and durability. The Green Mirror 580G polarized glass lenses use a copper base to enhance contrast and are particularly well suited for inshore, flats, and sight fishing. Costa lists light transmission at 10%.
