Perfect for an afternoon spent beachcombing or voyaging out on the water, Costa's® Ballast sunglasses are ready for whatever the day brings. Frameless and almost weightless, these Polarized Costa men's sunglasses boast a durable TR90 nylon and weigh in at a lightweight 16 grams. Whatever watersport or waterside adventure a day on the water brings, Costa's Ballast are always looking to uncover something new.

This version of the Ballast uses 580 polycarbonate lenses. They repel water and oils and block 100% UV, some blue light to eliminate haze, and yellow light to provide superior colors.
