Product Overview

Rimless sunglasses are extremely lightweight and provide an unobstructed view of your land or by sea.

Weighing in at a mere 16 grams (about half an ounce), Costa's Ballast Polarized Sunglasses are almost weightless, yet provide all-day protection from harmful UV light whether you're on the water or taking it easy on the beach. Their lightweight TR-90 nylon frames are made with resin from the castor plant. This bio-based resin offers a 70% reduction in emissions over petroleum-based resin, helping to reduce the overall carbon footprint. The 100% polarized, scratch-resistant 580P polycarbonate lenses eliminate reflective glare and reduce eye strain. Hydrolite nose and temple pads are up to the task of stopping annoying slippage and securing your shades to your face.
