Kevin H.wrote a review of Smith I/O X Interchangeable Goggle on March 15, 2013
Didn't ge to try this goggle on in my local shop. Thought it would fit great because the EG2 fit my face perfectly. Turns out the IOX is too big for my face, there's a huge gap at the bridge of my nose.
The lenses are amazing. The red / blue sensor mirror is THE best lense I've used. It can be pretty much used in all condition unless it's really really sunny. Would love to keep these but I might have to switch to the IO for a better fit.
