Sick Goggles!

  • Familiarity:I've put it through the wringer

Im going on my 4th year with these goggles and its so hard to let them go! with the wide range of lenses these goggles can be everything from your blue bird park goggles, to your low light pow/night skiing goggles! Not to mention i don't feel like i'm going out of my way when i need to change my lens because of how easy the lens's can pop in and out, yet they're sturdy and can take a hit! if you want a goggle that will hold for years, i HIGHLY recommend these!

for White/igonitor mirror/red sensor mirror mode, can I ask for changing the red sensor mirror to blue sensor mirror?

Hi Clara,

Unfortunately we're not able to swap lenses as they are already packaged by Smith. Contact me directly if you'd like a personalize experience here at Backcountry.



Looking Fly

  • Familiarity:I've used it several times

Have worn Dragon goggles and the past and enjoyed them, however these Smith's are taking over as my go to. Not only are they super stylish but they fit amazing and are easily adjusted.

I went with a mirrored green lense for the dark days and the bonus lense they sent me was a clear red lense for those dark days. 5X anti fog is gonna keep you scouting those fresh lines for days.

This was an easy buy since I received the bonus lense, can't wait to crush the deep with these!


I/Os Don't need an introduction...

  • Familiarity:I've put it through the wringer

These are the only goggles I've had over the past few years and they are perfect. Super versatile with two lenses. One for bright sunny days and the other for low light. Really easy to swap out and these goggles integrate perfectly with any Smith helmet, and generally pretty well with most other manufacturers.

Does the navy archive model come with two lenses? And if so which ones are they? I can't find a VLT for the lens? Thanks for any help!

Hey MountainMT,

The Navy Archive model comes with the Yellow (68% VLT) and the Extra Ignitor (35% VLT) lenses. Feel free to shoot me any more questions about the I/0 Goggles or Lenses.


Fits the smaller faces SO well!

  • Familiarity:I gave it as a gift but have feedback to share

These goggles fit perfectly and are the most comfortable Smith goggles around. The Triple-layer UltraWix foam is real soft on the face and doesn't hold that sweaty moisture like other goggles do. The "Black Sabotage/Blackout/Extra Red Sensor" are the best for those sunny Spring ski days out on the mountain. Love these!


Great for Small/Medium heads

  • Familiarity:I've used it once or twice and have initial impressions

These goggles are great. I got a pair after trying the I/O X goggles and finding that they didn't fit with my helmet or the size of my head. These, on the other hand, are great. They fit my face really well, and integrate with my K2 Rival Pro (size medium) pretty well (the push the helmet back a little bit, but it doesn't affect anything.) The lenses are great, really nice tints and color. The only thing I have a problem with is the face foam pushes up against my nose and makes it slightly harder to breathe through my nose, but I think thats just because of the foam not being broken in yet. All in all a really nice goggle, highly recommend

I am thinking of buying the Distruption/green sol x mirror/red sensor mirror goggles does that mean i would get the green sol x lenses as well as the red sensor mirror lenses

Best Answer

Exactly! The first color is the frame, the second two are the lenses that they come with.

Fantastic Goggles

  • Familiarity:I've put it through the wringer

These goggles are great! They fit fantastically with a smith helmet, lenses are easily changed, and you can see really well out of them. Can't go wrong with Smith!

Difference between these and the IOS AND IOX

Best Answer

Size of the frame.

IOS = Small

IO = Medium

IOX = Large


They're popular for a reason

  • Familiarity:I've used it several times

I got a pair just like everybody else, and I love them. They fit better with my older Smith helmet (less gaper gap) and the lense interchange system is easy. I can change them in about 60 seconds. Their frameless design does make them more prone to scratching though. But then again, they come with 2 lenses right out of the box, which is cool.



  • Familiarity:I returned this product before using it

Goggles seemed nice, but they had obviously been used and had a scratch on the lens. Backcountry had no other in stock so I was out of luck... El returno time.

Check the lens of new goggles throughly.


as amazing as everyone says

  • Familiarity:I've used it once or twice and have initial impressions

said it in the title. these are awesome. the interchangability not quite as easy as I imagined but it's still really easy :)

Great fit and feel

Great fit and feel

Love these goggles. I have a small face and have had trouble finding a good fit to not let in air on the fast cruisers during windy conditions. These are the best so far.

Best goggles ever!

Best goggles ever!

Fit is great, they never fog up, and they look pretty cool too.


Simply the best goggle out there.

  • Familiarity:I've put it through the wringer

I have had smith goggles all my life. This is my third pair of smiths, and I absolutely love them. First off, the two lenses for the different light conditions absolutely rock. The lens changing is easy, the helmet interrogation is genius, and the 3 layered foam is super comfy. These goggles provide excellent clarity and vision quality, and they are worth every cent. The helmet interrogation is absolutely genius, and it works great with other smith helmets. Overall, this goggle is amazing, great frame size for smaller faces, and has great lenses with great build quality. (I'm the one on the left.)

Simply the best goggle out there.

Hard to not love

  • Familiarity:I've used it several times

Upgraded from my late 1980's Oakleys. Paired with a Smith Maze helmet. Perfect integration with that helmet!

Got red sol x and a blue sensor. These things feel a bit "bug size" which I kind of dislike, but the field of vision is pretty good. I actually liked the Dye FOV better, but these had more comfort.

Foam was nice and cushiony. I couldn't see wearing these without the support of a helmet, as the weight of them make them fall down my face without being super tightly strapped in.

Red sol x worked good until about 6PM on a bluebird midwest day. Decided to go blue sensor from then and on then the whole next day. I actually prefer the blue sensor over the red sol x.

Changing out the lenses was ridiculously easy. Minimal fingerprints but those are easily removed.

Goggles have only fogged once on me, and it was a very wet, damp day.


Great For Everything

  • Familiarity:I've put it through the wringer

Great fit, ease of changing the lenses is a huge plus, I use these for everything from backcountry exploring to racing. 100% would recommend these.


Worth Every Penny

    The IO's are amazing I have ridden in every condition with them. They have held up amazing and have great lens clarity. They have only ever fogged up on me once and it was some freak thing with the lense. I would take the IO's anyday and they are a great choice for everybody. I am probably going to get the IO7 next year just for a little bigger of a frame, but the Smith IO is amazing!

    Worth Every Penny

    Best goggle ever

      Yes is sounds like a cliché to describe the Smith I/O's as this but it is entirely true. Smith perfectly combined comfort, quality, and style into this goggle. For example they sit on my nose so comfortably you sometimes forget that they are there. And I can't stress enough on how good of an idea it is to include two lenses. I wear my goggles on the outside of my helmet but I'm sure they fit great on the inside as well.
