Incorrect. The airbrake is much smaller than the I/OX, in fact, it's range of view is more similar to the crowbar and splice, while it's fit is a mix of the two.
The I/OX has a similar range of view compared to the Oakley Canopy, Electric EG2, and probably the Dragon APX, but I haven't tried on the APX.
Also, since the I/OX has a rimless design, it may look a tad smaller than the canopy. I love my pair, the lenses are really easy to swap out and they're comfortable. Having owned a pair of crowbars in the past, I can say I'm much happier with the bigger viewing window and different lens options.
However, I like the foam on Oakley goggles better, it's more comfortable and softer on the face. You really should go to a shop and try both on, because they're quite different goggles.
