Premium Polarized 580 Lenses*

Filtering reflective glare is essential for anyone on the water or outdoors. We sell only polarized sunglasses.

100% UV Protection

Your Costas absorb 100% of UV light, providing you the best in light management and protection.


Scratch Resistant and Durable

The C-Wall coating provides extra scratch-resistance and a barrier that repels water, oil and sweat for easy cleaning.

Inspired by the form and function of nature’s beauty, it’s no coincidence the Aleta sunglasses get their name from the Spanish word for “fin.” Offering water-ready performance in a stylish yet functional design, Aleta uses lightweight Bio-Resin and double-injected Hydrolite™ for a better grip. And with micro shields and hooding, excess light stays out while fog stays down with vented nose pads. Wearing Aleta, you’ll see the smooth shape and refined lines that don’t just stop at style. They’re best enjoyed when on, in and near the water.
