Do this google go good together with POC...

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.

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.

Fogged on day 1.

After extensively researching and reviewing goggles, I chose the Smith I/O as my fourth pair of goggles. I was disappointed that these goggles fogged on day 1. They are the first of my goggles that have ever done so. Thinking it was a defective lens, I switched to the lowlight lenses. They fogged also on day 1.

They fit my face well, though peripheral vision was not as good as my Oakleys or my Natives. The Smith I/O is not for me.

Its a hit

  • Familiarity: I've put it through the wringer

I am a big fan of Smith. I have used them on 30+ days of skiing this season and could not be more pleased. The I/O googles never fog on me, even when I am wearing my full face mask. One time I thought they were fogging on me, but turned out to be a heavy fog setting down on the mountain, not the goggles. They are very comfortable, I always forget that they are there. And lastly, the integration between the goggles and my smith helmet is great. The interchangeable lenses are a huge plus, my friends with only one pair of goggles are definitely jealous when they see me switch to a lens perfectly suited to the conditions. Instead of dropping a bunch of money on new goggles next season, I will just buy a new lens to play around with :)

IOX has much better peripheral vision

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

I noticed immediately that the IO's were too small and realized I need the larger IOX (Med/ Large). Just wish they would carry the "photochromic" red sensor lens at Backcountry, as It is truly the do it all lens at 20 to 50 percent VLT. Also found the lenses were difficult to get fully installed and appeared to get hung up on the strap outrigger. This caused the lens silicone seal to not fully rest on the lower frame and was annoying while looking down with my peripheral vision. This I suppose could be fixed with a little sand paper near the outrigger part of the lens. Uhggg. The lenses also smudge very easily. Not sure what kind of scratch resistance these lenses will take in the glades as this is a rimless frame and there's not much to protect them from the occasional tree brushing. Both the Oakley Canopy and IOX have the best vision out there, but still think Smith is the better value because they offer 2 lenses. The real value is the Smith Prophecy at half the cost and just as large as the IOX for great peripheral vision.
