Made for cyclists, on or off the bike, Oakley Sutro Sunglasses maximize your field of view while keeping your eyes safe for debris kicked up by vehicles. All Sutro Sunglasses feature Oakley PRIZM lenses, engineered to fine-tune the mix between individual wavelengths of color in order to maximize visual contrast. The Sutro is constructed from Oakley’s lightweight O-Matter nylon material that's extremely durable and resistant to sun and sweat damage.
