The largest frame ever developed by Oakley is still lighter than other big sunglasses rivals.

If you like beefy eyewear frames Oakley's 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 XYZ Optics® let you take in the view with complete clarity. Plutonite® lenses actually exceed ANSI Z87.1 standards for optical performance so your perspective stays clear even on muggy dog days.
