The Smith IOs is the Smith IO in a smaller size for smaller faces. It has all the same lens options the same tripple foam and a very similar look. The only difference is with the IOs you have to turn the device that holds the straps sideways to get the lens out which makes it a little more difficult. Still it’s not bad at all and a pretty easy goggle to change lenses. Two of our favorite lenses are the Photocromic and the Polarized. I have worn and loved this goggle with the new anti fogging lens for about a year and it hasn’t fogged up on me once.
Take the review of the Smith IO and make it smaller. This is a great goggle that doesn’t fog ant that is a tough thing to do for a smaller size.
