Description
The Costa Mainsail XL sunglasses deliver trusted performance, comfort, and coverage for life on and around the water. They offer a wide fit, micro side shields and integrated hooding to provide extra protection from sun, wind, and water. Vented nose pads improve airflow across the frame, which helps reduce fogging during long days outdoors.
The polarized 580G glass lenses cut glare and enhance color and clarity for a sharper view. They also provide 100% UV protection to help shield your eyes from harmful sun exposure. Furthermore, Costa’s C-Wall coating adds extra scratch resistance while repelling water, oil, and sweat for easier cleaning and lasting performance.
Built for water explorers, anglers, and outdoor adventurers, the Costa Mainsail XL combines premium lens technology, dependable coverage, and all-day comfort in an extra-large fit.
