    A simple look and crazy-complex tech—opposites really do attract.

    The Smith Photochromic I/O Interchangeable Goggles take a sleek, streamlined design with a wide peripheral view and dumps in the kind of tech that you'd  expect to see in a science fiction movie. The double-layered lens system stops fog and distortion to make sure you can see where you're going while the photochromic treatment takes these goggles from light to dark and back to make sure you're ready for whatever kind of light is coming down. It's almost hard to imagine that such a straightforward look could be packing so much heat.

    4 Days Of Skiing Before The Season Ended

    • Familiarity: I've used it several times

    I've only used these in fairly spring like conditions, and had no fogging issues. Probably the coldest they saw was mid 20's but all was well. I've only used the Photochromic lens and it performs well. It does't get crystal clear at night, but it's usable. It doesn't get super dark in the day, but it knocks the brightness down enough to keep skiing enjoyable.

    A girl's gotta have options

    • Familiarity: I've put it through the wringer

    Favorite thing about these goggles: multiple lenses! I love having choices for the many different weather patterns the Northwest throws at me. It is easy to switch between lenses and I love having so many to choose from.

    This is my second pair. Fun fact: they are not puppy proof! And I would keep buying them.

    Second thing I love about these goggles: easy to adjust, no slip fit, and amazing comfort.

    Third and final praise: they aren't huge! They don't take up my whole face and give me good visibility.

    Great google

    • Familiarity: I've used it several times

    I have been able to use these a couple of days this season already. Overall, I have been really pleased. The lenses are great in sun and shade, transitioning seamlessly between either. They are comfortable and provide great eye coverage. From a design and aesthetic standpoint, they look great.

    Photochromic is Phenomenal!!!

    • Familiarity: I've used it several times

    No matter which style goggle you choose make sure you choose the Photochromic lenses! These lenses are unbelievably versatile, from white out conditions to bright blue bird days and everything in between these lenses allow you to have crisp clear visibility.

    The lenses actually change, so when you pull them out of the box and on grey bird days they will look more like the red sensor lens, but when you hit some light they turn more into a solar x type lens (and have the mirrored looked to go with).

    All and all I have never been so excited about something so seemingly small, but this is something to get excited about!

    Great goggle and GREAT service from BC

      Very comfortable goggle with decent adaptability given lighting conditions. I used to use Zeal's photochromatic goggles and there are on par and give me a different tint than the more gray/black of the Zeal goggle. I had a slight glitch with my I/Os however, but backcountry service took care of it right away - you guys rock.

      Very comfortable

        love these goggles, photochromic lens don't go very dark in bright sunlight which I really like about these lens. So far no issues with fogging and very good view as well, much better than my previous pair of goggles.

        Very comfortable

        Fogging issues

        • Familiarity: I've used it several times

        I have had several fogging issues with this lens. I used a anti fog wipe (which i know you shouldnt) which seemed to help. But these lens seem to fog more than they should. The photochromic lens works okay. never seem to notice a huge difference from light to dark. I often think they should be darker than they are most of the time. I have a small face and the frame fits well.
