If you like beefy eyewear frames Oakley's Polarized Monster Dog Sunglasses have you fashionably covered. This is the largest frame ever designed by Oakley but it's surprisingly lightweight. Whether you're sailing hiking walking or just cruising around the patented and polarized XYZ Optics® let you take in the view with complete clarity and minimal glare. Plutonite® lenses actually exceed ANSI Z87.1 standards for optical performance so your perspective stays clear even on muggy dog days.
