Best Goggle Out

  • Familiarity: I've put it through the wringer

These goggles are bomber. Huge range of vision with super sick lenses for every condition. The clip on the back of the strap is super convenient and the lenses are really easy to change out. Cant go wrong with Smith goggles!

Comfortable fit, Peripheral to the Max

  • Familiarity: I've put it through the wringer

I've used the I/O for the last 3 seasons and they are definitely one of the tried and true pieces of equipment I own. The lenses are incredibly easy to change in a pinch, I've even done it mid lift ride. They are made to interface well with any of the Smith helmets. I've used them with both the Vantage and the Maze - no gaper gap. There are tons of lens options as well which make the I/O super versatile no matter which frame you choose.

Best Goggle Out There

  • Gender: Female
  • Familiarity: I've put it through the wringer

I love these goggles so much. They come in so many great styles, and stay in really good shape for a really long time. The lenses don't easily fog up and they lenses are super easy to change. They have an amazing venting system. I am a competitive skier who travels and skis throughout the whole winter and my I/O have managed to keep up with my needs and continue to impress me every single ski season. They fit really well with any Smith helmet, but I definitely recommend the Maze the most. Get these goggles if you are looking for a good time.

what is the best lenses for the i/o .for snowy and really cloudy weather

Responded on

Hey Kim,
For low light conditions, you'll want a lens with a high VLT (visible light transmission). Any of the Sensor lenses would be awesome - Blue Sensor 70% VLT, Red Sensor 60% VLT, or the Yellow Sensor 65% VLT.

Do this google go good together with POC Fornix small size helmet?

Best Answer Responded on

I usually like to stay with the same brand when choosing helmets and goggles. Of course these will work, I just think the helmet and goggle are usually made to fit better when you stay within the same brand.

These goggles fit perfectly with the poc fornix!

Hi What size Smith I/O goggle works best...

Hi What size Smith I/O goggle works best with the Smith Variant helmet (medium size) My face size would probably be medium to large? Thanks

Best Answer Responded on

The I/O sounds like it would be perfect. This goggle is meant for medium to large faces, the I/O X is bigger and will provide more peripheral but, it might not fit the best. The I/O S is for small to medium faces, I would say if your in the middle of the range go with this. If you are worried buy both the I/O and I/O X we will provide you free shipping to get a pair back to us as long as they are new.

Comfy and Reliable

  • Familiarity: I've put it through the wringer

The i/o goggles are spot on. Definitely great for small to medium sized faces, the flexible frames wraps around your face snug. The ventilation pared with the double lenses mags fog issues less than with other goggles. I use about one lens all year, skiing everyday and without fog or negative visibility, just treat 'em right (dry them at night and regulate moisture while out and about). The red sol-x lens is my all time favorite, works in flat light and sunny conditions!

These are great goggles, probably the best i've ever worn. They fit so perfect to my face while not being bulky at all. Very easy lens changing system and there also super durable. I took a bunch of nasty spills and the frame is still fine and smith even gave me a brand new lens after scratching mine.

Love em!

  • Familiarity: I've put it through the wringer

I liked these goggles so much I bought a second pair when they were on sale for around $60 on SteepAndCheap. They don't fog up, the lenses are easy to replace, they look cool, they keep my eyes safe. I suppose they are a bit on the pricey side, but they're definitely high quality.

Only time I had any issue was in very cold conditions (-15F), the moisture coming off my face started to freeze on the inside of the lens, but I'm not sure there's much you can do at about it at that temperature. It only happened later on in the day, as well.

Both pairs I got came with 2 lenses and a very nice goggle pouch. The mirrored lenses are way cool looking, but honestly the non-mirrored are more practical once you hit that 3pm flat light.

Initial thoughts

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

I think I just bought my third pair of the I/O line and purchased these in the White frame with the red sensor mirror. I get the same old feel. I have a very narrow face so I do have a hard time finding more expensive goggles to fit my face. Usually the corners of my eyes have exposed air coming through because goggles do not seal. These extinguish that problem all together. These goggles provide a huge plain of view. I get a much greater field of vision and it allows me to use my periphery much more effectively. The lenses come in and out pretty easily, however it is no Anon M2 or M1 (but none on the market are right). What I do not like about these goggles is that the snap is directly on the back of the band and they awkwardly fit through my goggle clip on the back of my helmet. Huge bonus of the strap is it has a silicone rubber strip around the inside which helps keep my goggles up. My last pair of I/0 did not have this and would come down from time to time. This helps keep my goggles in place when I am really bouncing around. So much appreciated SMITHOPTICS. One last note, I use these with a POC receptor backcountry and they fit my helmet very well, no gaper gap! I have used them in the past with a Smith Variant and the fit was solid as well. Right now the price on these is a steal. The only place you will find them cheaper is on Ebay. I hope this helps you guys out.

Does this come with an extra lens? The Sage version states it does but I don't see much for info regarding that on this I/O.

Hey Johnathan,

This does come with a spare lens. In the dropdown menu the Extra in that variant title refers to the bonus lens.
