I opted for the I/OS since I have a narrow face and usually have a hard time finding sunglasses that aren't too wide. I love Oakley products but the hype about the Smith I/O swayed me this direction. I don't regret it. The fact that they come with a second lens is also a bonus. I have yet to scratch the one on them though. They're comfortable and don't fog up. Highly recommended.
