Before I bought my Giro's I bought the IOX based on reviews and a friend but they didn't even cover both eye sockets. As big as they are I'm not sure why the don't offer a wider goggle.I checked, my Oakley are the Air Brake XL with Hi Pink and Sapphire Iridium. Although darker, I was amazed how versatile the latter were on mixed days. I still want to try those Smith Storm Yellow on a snow puking day! The IOX does feel smaller than the Air Brake.
