Venting/Fogging
In testing, we didn’t experience any fogging with Smith’s Vapor Lens technology and Porex Filter. There is good venting all around the goggle frame.

Field of View
There is a good field of view for what Smith calls a “Medium” size frame, but nothing exceptional and certainly less expansive than “oversize” models.

Lens Quality & Options
The 7 has many options, most of which are mirrored, allowing for seemingly endless combinations of lenses and different colored frames. The spherical Carbonix-X lenses are high quality, but nothing exceptional in terms of clarity.

Frame and Construction
There is great flexibility and structure to this frame, but the multi-step interchange system is far too labor (and fingerprint) intensive. Many competitors’ interchange systems are easy to execute on a ski lift, but the I/O 7 takes far more time and effort than most other goggles I’ve used. Also, while some may like the buckle on the goggle strap, it’s placed dead-center where most helmets have a clip for the strap. The goggle strap buckle under the helmet clip renders some helmets incompatible with this goggle.

Fit
The strap connects to the frame with a great “dual axis” outrigger that makes for exceptional flexibility. This resulted in a good fit on my face and in my helmet.
