Costa Cook Prescription Sunglasses, Best Women's Sunglasses

Costa Cook in Palladium with Blue Mirror lens

To give you a taste of what Costa has to offer, first have a look at the Costa Cook. These unisex, large fit frames are classic aviators with oversized lenses that we've reviewed here. But don’t let their size fool you. Made with Beta Titanium material, these frames are lightweight and rest comfortably on your face and stay put with Costa's Hydrolite technology. And don't worry about taking these out for a long ocean cruise, the titanium frame has amazing corrosion resistance.

Costa Caballito prescription sunglasses

Costa Caballito in Shiny Black with Grey lens

Like Costa Cook and Piper, the Costa Caballito is designed in unisex fashion.

Likewise, the Costa Caballito is made with that heavy-duty nylon for enhanced durability. It's the perfect blend of lifestyle and performance. If you are looking for more performance, consider the Costa Fantail. We did a review of both right here.
