I'm a big fan of Oakley sunglasses.  I own  Monster Dog and a Graphite Hatchet models and my wife got me this one, Scalpel, wich look great, but the frame is Brown Smoke, wich is a nice color, but the material feels so weak and cheap, you could think Oakley made a mistake.  I wish she had ordered on other material, because this one is not good at all.
