Styled for dedicated anglers and aquatic adventurers, the Costa Bloke Mirrored 580 Glass Polarized Sunglasses are perfectly suited for regular folks who like to spend tons of time on the water. Extra-large shaping offers optimal coverage from the searing sun when you're on open water, and polarization eliminates glare so you can spot fish and enjoy scenic views more clearly. Speaking of clearly, the glass lenses offer superior clarity compared to polycarbonate lenses, so you can enjoy everything in crisper detail. Plus, glass lenses are also more scratch-resistant, and Costa's glass lenses are thinner so you don't get the fatiguing weight often associated with glass lenses.

The mirror is encapsulated between glass layers so it can't get scratched up. Cam-action pin hinges and a chip-proof finish provides dependability during demanding journeys. And since you don't want to lose your favorite shades to the depths, Hydrolite nose and temple pads provide a secure, comfy fit to keep the Blokes firmly on your face in rough waters.
