I love the I/O goggle, the evolve edition is made from mostly recycled plastic, and the super quick interchangeable lens option is sick. I can change a lens in seconds, on the lift, at the top of a line, where ever; it's fast and sweet. They have great peripheral vision, and fit perfectly with smith helmets. With the updated face foam they fit better when worn with a hat to.

I love the fit of these goggles, feels so comfi and nice. Lenses are badass. 5 stars all around.

k, so here's my deal with the I/O-- for those of you that struggled with getting them dialed when you bought them last year and were super stoked to have SUPER EASY lenses to change "the firstish no frame google" ---AND WERE disappointed? THIS COMMENT IS FOR YOU: Smith worked out the bugs--- check em out now--- if you don't want to spend the doe right away-- try someone else's on-- the fit is better, the foam has changed, and the moisture issues have been ironed out a lot... so give them another chance before you say "no". They ROCK.

I've been using Smith goggs since I was in diapers and this is my favorite one yet. They offer the biggest, most unobstructed field of vision I've seen along with the best style. I'm hard on my gear, and one of the things I had to learn was to keep my hands off the edges of the lens since its not as protected by the frame as in a conventional design. Easy lens change, hardly ever fog unless you mistreat them... I mean do I need to say more?

So I just got my I/O Just as the first snows fell in the cottonwoods. I went hiking up at Alta for some early turns and after working hard and sweating quite a bit, I threw on my goggles and charged hard down the hill and didn't get the slightest hint of fog. I repeated a few more times and still nothing. No fog and they fit great! I'm totally sold!!

Gotta love my Smith I/Os. Rocked them for a full season and I have no complaints, I don't find that mine have the wind through the bottom while going fast problem. The optical clarity is so good, better than my Oakley A-Frames I find. The change is super fast and easy, and comes in so handy up in northern BC where the weather goes from sunny to white-out in a matter of an hour. They fit incredibly well with my Giro G10MX, gone is the gaper gap. The two lenses that come with it, the Sensor and Platinum mirrors, are the perfect two lenses to have, Platinum in the bright morning sun, and the Sensor for those white-out and cloudy days, and nights. The foam is super plush, and feels so comfy.

I absolutely love these goggles. I have a few of these (one for riding and one for backup) and have never had an issue. They breathe wonderfully and never fog up. What I like most is how easily the lenses change out. With the flip of the switches on the top you can pop out and replace the lens with whatever kind you need for the type of day it is. I would definitely recommend these to anyone looking for a top quality goggle with high functionality.

No need to beat a dead horse here, but smith has another seriously happy customer. Unmatched fit and optics, swapping out the sensors for the sol x when the sun comes out couldn't be easier.

When I first tried out these goggles I was not a fan and before very long I went back to the Phenom because of the better fit. Last year I tried them again thinking maybe I was just used to something else and didn't like the new feel, but again was disappointed. These new ones however have been modified in a couple of very simple but productive ways. The foam on the sides has been thinned out and the foam in the nose area has been thickened up to make a much better fit all throughout. Finally on the third try I have been very impressed and have been using them every day.

the best goggles o have ever had. better than the crowbar from oakley. very easy to change lenses and has great vision. sick looking with the platinum lenses. no fog at all on the lenses with little ventilation. goes great with the smith variant brim helmet. perfect and i mean perfect combination. no gaps where air can get through as i had heard. crashed in the pow couple times and now snow slipped passed these goggles. would highly recommend even thought a little pricey. very much worth it.

This goggle is very cool. Not only does it well ventilate, but it's so easy to switch your lens with the extra lens it comes with. When I bought this goggle I though that was it. Oh no, it comes with an extra lens for foggy days, a soft goggle bag, and a hard shell goggle case with extra storage for multiple lenses. I also own the Variant Brim helmet and with the two combined I have yet to have any unnecessary fogging issues, even when skinning in the backcountry. To sum everything up, this goggle has it all!

At the start of the 08-09 snow season I bought a pair of A Frames and I/Os. I took them up to Abasin in CO at the start of the season. So I did a quick 4 lap run using the both. 2 runs with the Smiths and 2 with the Oakley's. I interchanged the lenses after each first run. The I/Os were lighter, quicker to change and come with a nice carry case. Great package for the same price as one pair of A Frames Love the extra vision you get from the open lens. Con: The light-weight body of the google does not seem durable. Didn't like the clip on the band. I know it is to help you put them on a helmet with out having to strech the band then tighten it back up, but the connection seem very cheaply designed and manifactured.The Aframes wer a little more difficult to change out lenses, however when your on a lift that takes 10-15mins to get to the top you got some time to be doin things on the wait. The body felt sturdy and sound.In all I was sad to say that the thing that made me choice Oakley over Smith is the lens. I truely feel the science and materials behind Oakely have bench marked the Optics Industry. Now if only Oakely could get there clothing right...

Best I've ever used. Bottom line, phenomenal. There is a reason why I am the 100th+ comment with positive stoke for these lenses. The styling is a little outrageous, but the visual clarity and the field of view makes them a critical users dream. Buy them. Wear them. Love them.

I have the Wallstreet version of these and could not be happier on the looks. The function of the goggle is even better!!! I don't know what the problem is with some of the reviewers that have ventilation problems, but i board in Colorado where it is dry and they are phenomenal! I have also been to Whistler for a week and never had a problem, even with the foggy skies, thick dew, and wet snow! I could not ask for anything else. Plus i have used the Prodigy and the Phenom and the interchangeability of the I/O is sickly fast. I mean they are changed by the time my friends get their boots on at the car!!!

I had these last season and had the air coming in around the nose problem like others have mentioned. They've changed that this year by thickenning the foam thus providing a better seal. Tried on a pair, had my girl take a look from underneath to see if there were any gaps. Nada. Great value too with two lenses and the hard case.

I first bought the Oakley Splice's and they pinched my nose a little too much. I have a slightly bigger than average nose, so maybe that was it. Bought the I/O's and couldn't be happier. I grew up on the East Coast and never wore goggles before. Just didnt like them on face and i could read the bumps as well with them on. The I/O's changed my perception of goggles all together. the default lense worked great in the sun and in the overcast too. Fits great with my Smith Maze helmet as well.

my IO's were too tight on my face when I wore my smith helmet(variant brim). I would have the goggle line for 3 to 6 hours after riding...it was pretty bad having smith tattooed into your forehead for the rest of the day....

Bar none, sick visibility, sick interchangeability, sick helmet adaptability. Comes with two lenses, and I would suggest adding one more; the gold mirror sol-x for sunny days. Perfect clarity and you only have to haul one pair of goggles and decide when you get to the hill. Never had any issues with fogging, but then, I'm not a mouth-breather. I like Oakley's and EG2s, but this is the goggle I wear every day.

Wondering why this costs so much? Awesome goggle with a sleek look, great field of vision, and has a clasp in the middle of the strap for easy on/off. Includes BOTH an Ignitor Lens (for bright light) and a Sensor Lens (for low light) both with the dual-layer tech with a filter to minimize fogging. Includes a goggle bag. Includes a HARD case that has a section for extra lenses! Now do you get why this costs so much? :) This is a badass goggle package with two great lenses from Smith that do their respective jobs very well. The only thing I think this needs is a clear lens for night skiing, which can be bought I think for around $25 last I checked.

Excellent quality goggle from Smith. Very easy to change between the platinum mirror and sensor mirror lenses that are included. No problems with fogging or vision in all light conditions. They fit flawlessly with my Gyro helmet. No complaints regarding the performance or large style of the goggles. The only reason I rate this goggle at 4/5 stars is because they arrived with a notable scratch on the mirror lens. Not sure whether this Backcountry's or Smith's fault, but if you're paying this much money for goggles the should never arrive blemished. But I would still recommend this goggle to anyone, assuming they don't arrive scatched like my pair.

Looks are top notch, I have a large face and they are a tad tight, but you can't beat the looks.

The problem is that these had catastrophic failure in the fogging department. I ended up in a blizzard on the top of Alpental and I couldn't use my goggles, that was not fun going down 'Nash without goggles. Now, I am a sweat hog, I admit, but these were fogging the first day I got them. I don't wear a helmet and I have a decent Fro, that may be the reason for the fogging. I've been told if I wear a helmet that it may help, or if I cut my hair, that would help as well, but that's not gonna happen. I ended up giving the goggles away to a guy that is a more of a sweat piggy, not a full fledged hog. He has better luck with them, even though he had to take them off on the lift to reduce fogging, but as soon as there is airflow the fogging slowly goes away.

I used my bro's Turbfans, they worked great so know I have some prodigy turbos on the way.

So, if you are a sweat hog yourself I would recommend going with the turbofan or just a different goggle period, if not, enjoy.

I got these after trying the "interchangeable" Smith Prodigy goggles. Those are nice goggles, but you need a workbench and about 15 minutes to actually get one set of lenses out and another set back in, and the little pieces are probably easy to lose. Not something you're going to do on the hill, or probably even in the lodge at lunchtime.

These, on the other hand, have a lightning-fast quick release system that lets you swap in a new set of lenses in a hurry. Need to deal with changing weather conditions? Just tired of the lenses you've been using? About 30 seconds and you're good to go.

The frameless design is a little different, but actually looks really good with most helmets. (I have a Giro G10 right now, and it works perfectly with it.) No problems with fogging for me, even in springtime conditions.

These come with *two* lenses, "Ignitor Mirror" (all-around) and "Platinum Mirror" (bright conditions). The full line of replacement lenses are available from Smith or some other online resellers. I also picked up "Sensor Mirror" (flat light) and Clear (night skiing), which should cover just about anything.

Smith killed it on these! I love how easy it is to change lenses, the range of vision, and the style! I had these gogs last year and bought a second pair this year because I like them so much!

I've been out a few times with these googles and I have to say that they met and exceeded all of my expectations. Truthfully, I wouldn't have known that I was wearing googles until small specks of powder got stuck to the lenses. Well that might be a little bit dramatic, but that's how blown away I was by not only the incredible field of view these googles provided, but also their superb glare protection and their overall comfort level.
Unlike some of the others who have reviewed this product, I had no problem with fogging due to ventilation here in Minnesota or out west in Colorado.

The I/O are awesome. They fit great on my face as well as with my Smith Variant Brim helmet. The peripheral vision is excellent and the lenses are easy to change. Definitely recommended.

That's what I kept saying to myself on my recent ski trip with these, using the ignitor lens multiple days. I loved them. Fitment was great, absolutely zero fog, great clarity, and the ignitor lens was fantastic from dawn to dusk. I reeeeeally like the hard case it came with too that holds the gogles AND the sensor lens for overcast days (which i'm familiar with as I use it on my smith prodigy goggles I replaced), and has a few more slots for other lenses. Just a great product... just try to catch it on sale :)

I bought these goggles because I wanted the best goggles on the market, period. These offer huge visibility, great lens quality, interchangeability (which is saving me from buying 2 different goggles), and they look cool too.
However, there are some downsides to this goggle. If I'm skiing hard, they tend to fog up in the afternoon (regardless of temperature) because (presumably) they're not venting moisture. They lack frontal vents, and on dry days, I find myself airing them out on the lift. On moist days I just look through the slowly-developing peripheral haze.
With this lack of ventilation in mind, I have realized that I could buy two pairs of Phenom's for the price of the I/O's, which means that in the case of a crash, I could whip out a second set of goggles that are completely snow-free. Replacing the lens on these doesn't remove snow from the rest of the goggle. I have since Purchased the Phenom's, and the visibility is similar (though not quite as good top-bottom).
So, considering the cost and the lack of lens vents, if you have a tendency to fog up goggles like myself, I'd recommend 2 pairs of Phenom's instead. However, if you don't work that hard on the slopes, or find that your goggles never fog unless you crash (and you don't crash often), and you want to look freaking cool, then get a pair of these!
Oh, it's worth nothing that both these and the Phenom's fit my nose better than any other goggle on the market. I broke it as a child, and have had a more prominent bridge ever since. This means that most goggles/eyewear don't fit me without constricting nasal airflow. Even with a helmet pushing these down a bit, these (and the Phenom's) are the only goggles that have a wide-enough nose hole to make a comfortable, non-constricting seal over my nose. Because of this, I will heretofore always look to Smith for my goggle needs in the future. We don't all have long, skinny noses!

I got these goggles since my cool Native goggles pressed my nose closed when wearing my Giro MX helmet. They solved the problem, look cool, and offer great vision. Just last week in Keystone I switched to the lighter lens for a gray snowy day and I'm sure it helped. I'm a bit concerned about banging them up because the don't have a frame which could double as lens protection and I wish they were polarized but they really are great goggles.

I had these out for a couple days. Optics are excellent across the whole range -- very pure, no blurring or aberrations. Field of view also is excellent, very good peripheral vision. For fogging, compared to my old gogs they'd get more momentary fogging, but it would dissipate immediately. On my second day out, when it was more humid, they took a microsecond longer to clear, but they never did fog up. I haven't tried them on a true fog-fest powder day, though... we'll see. Best of all, on day two it went from bluebird to total cloud cover as a storm was blowing in, so I was able to simply pop in the lighter lenses... it's awesome to have that flexibility. In terms of fit, they work perfectly with my Giro 9 helmet. However, when I tried them on in the store with the Giro 10 and Smith helmets, the adjusters at the back of those helmet pressed into my neck a bit as the goggle is so tall. That will vary by head shape, but keep it in mind.

I tried several goggles before pulling the trigger on these. The I/Os are great. Great field of vision, comes with two superb lenses (bright and low light conditions), good fit for my medium face, dont fog, and look cool- kinda a darth vader look with the big mirrored lens but not over the top. Come with a very nice hard case to store your investment. Five stars

The 08-09 model finally has proven to me that God exists. I've struggled to find a google that will not fog. No ifs, ands, or buts. The IO stops fog. Only trouble I've had is skiing super wet pow days in Alta this Jan when the vents on top got clogged and some fog happened. As soon as I cleaned the top vents and wiped the inside lens, poof! Presto, a perfect, wide-perspective google w/o fog again. Big Fan.

Just wore them six days in Aspen/Snowmass. With constantly changing conditions, they were very easy to switch between the two included lenses. They did fog briefly here and there, but fog went away on it's own within seconds! I would highly recommend these goggles. Great Fit, Feel and Field of View!!!

No Fog, super great fit, wide view, bad ass look, Interchangeable Optics (cause you will scratch them up) what more could you want !
I Like !!

they fit great, I have big noise, and they still fit great ! fog no more, crazy it's like science fiction, and the lens, wide, big clear. you can also swap out the lens fast and it comes with an extra one.
plus they look bad ass !!
Not cheep, but when your out doing your thing, and they work and feel good, you will say like me, they were worth it.
Off to Tahoe soon, if they still rock I'll post more, that will be the true test.

These things are great. They have never fogged up on me and i love the ability to quickly swap lenses when light conditions change. Nothing worse that catching an edge snowboarding due to flat light conditions...never again with these lenses (Assuming you have the appropriate lenses for swapping out) Easy swap out of lenses doent mean you need to buy new goggles when you take an evergreen branch to the face while pillow poppin the glades. Fits on a helmet nicely. Doesnt hurt the bridge of nose. Cant even tell they are on the face, except when you look in the mirror and notice that gnarly goggle tan.

I wish they would make a smaller women's version of these googles. It really does add a lot more visability but way to big on your face with the mirror lense.

smith i/o goggles are well constructed, comfortable and stylish. super easy to change out the lens, super nice that two lenses are included! where they miss the mark a bit is that they tend to leak a bit and cause a draft around your eyes.. the main issue w/ any goggle is fogging, while these do a better job than most they are not immune from fogging.. when the industry figures out how to totally eliminate fog, we will be golden...

Nice goggles. Great optics and field of view. The only complaint might be that there might be too many vents, as the fit was great but I could feel air hitting my face at times. Then again it was an extremely windy and cold day (lifts shut down, severe frostbite warnings and all of that).

Best goggles I've ever owned. Stay unfogged in worst of conditions. Lenses are easy to change. In certain cases where wind is uphill you get a little cold wind in on your eyes, but it's a small price to pay for goggles that stay unfogged.

I played with these goggles for the better part of 70 days of snow last season. My set up was with the variant brim helmet and with this i say AMAZING integration. No goggles gap and looked super cool. Pros: easy swapping of supplied ignitor and sensor lens. Super wide field of view. No rims, all lens. very nice. Cons: lens latch broke in freezing weather, super disappointed. Depending on the shape of your face, sometimes had a gap around the nose area. Had to wear them lower on face which gave more room for goggle gap up top. I sent them back along with the variant brim at the end of the season. I was torn between getting the updated 09 models but decided to stick with Phenoms and Hustle helmet. Cheaper and proven!

these are the first goggles i have ever readily changed the lens out when the light changes without some dread about getting the it back in. the vision huge and clear. i have used all winter without a single fog issue. in this endless powder cycle they have been dreamy!

I just got a pair, and they were excellent on the first day I used them. Used to have the POC lobes, which I loved for their field of vision and style, but had a fair amount of fogging issues with them. The I/O's would fog very briefly but dissipate immediately. Would highly recommend.

These things rock! Sensor lense is great for those low-light days and the Ignitor works for everything else. It's a total 2 for 1! Wahoo. Anyway, I've tried to get these things to fog and haven't had any luck aside from taking them away from my face and breathing steam right in to them. Best goggle I've had. No distortion. Fit well with both my helmets (a Salomon and a Protec). Snatch a pair while you can...

Sweet, sweet goggle. These have the most comfy face foam that I've ever used, fit my Smith Hustle helmet (http://office.backcountry.com/store/SMI0490/Smith-Hustle-Helmet.html) like they were born there, and have the best peripheral vision of any goggle on out there - hands down! After a few face shots (okay, it was more like crashing on my face) they didn't fog up a bit. I had heard that the quick release system ended up making for a goggle that was a little more 'touchy' when it came to fogging. I had no such issues. They did fog up some when sitting up on my beanie (all goggles will) but they de-fogged themselves in a few seconds once I got moving. Skiing switch is a breeze with the frameless design. You don't need to turn your head much at all, just a peek over the shoulder is all it takes to get a good visual thanks to the peripheral vision of these perfect goggles. They are spendy, but don't forget that you'll get your goggles, two lenses, a goggle bag, and a case to keep it all together. Pretty money!

I have used these goggles for seven days of skiing in Colorado. Variable conditions from bright sunny days to blizzard white outs. They never fog and fit perfectly with my Giro helmet. The interchangeable lens is the best. Smith gives you two lenses. The second one is for low light and works great. The change out is quick and easy. I am thinking of getting a slightly darker lens for bright days but that may be a little gear geek and over the top. But hey, the lenses are easy to swap and store.

Changing lenses, it sucks (ahem...Oakley). If you think it really sucks and you have the right kind of face, then this goggle is right up your alley.

The switch is simple: Flip up the top tabs, pull off the top, pull off the sides, then pull off the bottom part of the frame. BOOM! The lens is off! To stick a new lens in, just go in reverse. Without a doubt, the easiest lens changing system so far in the industry.

There is more though. The amount of vision you get top-to bottom and peripherally is surprisingly large. It also comes with either the Ignitor lens (a decent all around to sunny lens) and the Sensor Mirror lens(one of the best low light lenses in the industry).

Now for the bad, there isn't much. The frame is definitely for the larger faces out there and a small amount of people have complained about an annoying amount of air coming in through the bottom.

Overall, those people with bigger faces and problems switching out lenses, prepare for Nirvana!

Peripheral range is second to none. Color schemes to match any kit. Optics is on par with the "O". But, and there is always a but, these bad-boys will fog during those 31 degree pow-days. The I/O's, like any goggles will fog up faster than a fart in a one-piece if you are prone to the sweatstacio like I am. If that is case, go turbo. Smith prodigy turbo.

These fit great and the clarity is really good. No fog.

These are cool looking, super light, and there a ton of color options, with all that said they make a great goggle when wearing a smith helmet or any helmet, however if you wear a hat get ready for some chilly eyeballs and alot of watering eyes. Not sure how fast you ski or ride but it doesnt take much speed to get the air flowing in these things and really messing with your eyes, I had some pretty horrible experiences with these goggles when I just had my hat on, this is the biggest take back I think in these goggles, however wear that helmet and you should be fine. The problem or should I say the issue is that there is a small gap where the lens and the frame meet its' great for non fogging, but when there is no helmet above it to direct the air the correct way then it just becomes cold, and annoying. They looks sweet tho!

These 'ere gagles are the bees knees. Seriously though, used them on a couple of occasions and they perform great. They defog really well, despite what it may look like, and they have an excellent FOV. Really where it comes in to play with smith though is the Sensor lens. They are amazing. They provide some of the best low light, poor vis, definition that I've seen in a goggle. Seriously consider picking up a pair of these or the Phenoms. All in all I like the Phenoms a bit better as they seem to stay fog free a bit better.

I hate not having complete field of vision and my old goggles spent many a days on top of my head; instead of covering my eyes. Coming home from the mountain day after day with serious eye fatigue though I decided I needed to actually get some goggles and wear them. The Smith I/O goggles have the best field of vision I have seen. The only obstructed view is right at the bottom of the goggle and the bridge of the nose. I can live with that since they save my eyes the strain and will hopefully save my nose from breaking in my next inevitable face plant. Any fog that builds up clears almost instantly and they come with two different lens which are seriously easy to replace... Unless you're like me trying to do it driving down the interstate in the pitch black dark. Don't do that.
