Product Overview

Extra large frames and polarized polycarbonate lenses for wide faces and wide open places.

Aye, this Bloke might be big and tough, but he's a regular gentleman when it comes to protecting a chap's eyes. These extra-large sunglasses are just as durable and reliable as your best chum thanks to their heavy-duty TR-90 frames 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. 100% polarized, scratch-resistant 580P polycarbonate lenses ensure you'll be the envy of all your fishing buddies. Costa's bilateral fusion technology fuses two colors together in one frame for a chip-proof finish. Whether you're battling trophy tuna or just taking in the view on a dinner cruise, the Hydrolite nose and temple pads will keep them firmly on your face.
