Tyler Hornewrote a review of Smith I/O Interchangeable Goggle on March 12, 2013
I have been wearing the Smith i/o for the last 4 years and I don't feel there is a better goggle out there. The lenses are incredibly easy to change, I use mainly the black out for the sunny days and the red sensor mirror for the low light storm days in Jackson. The fit is also great they fit perfectly with my smith maze helmet, no gap whatsoever. Would definitely recommend them to everyone from the die hard local to the 5 day a year tourist!
