    Fisherman's friend.

    Off the coast of Baja California, Magdalena Bay has mangrove-lined swamps, fertile estuaries, and some of the best sport fishing in the world. The extra-large fit Costa Mag Bay Polarized 580 Poly Lens Sunglasses were made for big adventures in a fisherman's paradise—wherever you find one.

    The extra-large fit provides plenty of protection from the sun to reduce eye fatigue when you're staring across the water all day. The heavy-duty frame is made to take a beating but is also lightweight for a comfortable feel. The lenses block 100% of UV light, and they're polarized to eliminate glare from the surface of the water so you can spot your target more easily.

    • Q & A

    Large heads and quality lenses

    • Familiarity: I've used it several times

    Ideal for "XL" head sizes. I tried several pairs of Costa's and other brands, even those sized for "large" and "extra large" heads. The Mag Bay frame was the most comfortable fit for my big head. The Costa lenses also provided a crisper image quality and contrast compared to similarly priced competitors whose style I liked a little more. These are great driving sunglasses, as well as hiking. No slipping. The brown lenses do have a quirk. Certain sun reflections on surfaces, such as water and even the dash of my car, appear shiny red.
