Product details

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.
