They are not polarized, nor are they mirrored. It is a orange amber colored lens made for "all conditions" light use.

They should still work. The area for goggles in the G10 MX is pretty big, it might be tight though, but it should work.

Ive got the smith holt helmet and i havent had any problems wearing these goggles with it. You might have to move the helmet up a little bit, but you will not even notice.

prodigy is biggest, I/O is probly the "best"

What is smith biggest and best goggles? Electric eg2 looks very cool and large wiew interested me. My smith holt is size L so i dont have smalest head. Have anyone more experience about Electric eg2 with smith holt helmet.

Sorry i mean SMITH HOLT helmet

Hi! Why did you keep EG2 so bad goggles? And what you mean "-most lens choices are completley mirrored as opposed to kinda mirrored like the eg2's" Is EG2 lensses not completely mirrored? But what is it matter if visible light transmission is okay?

GREAT QUESTION!

...so the eg2 beats the Feenoms in these areas
-the "holy @$#% look at those huge goggles!!!!!!!!!!" factor
-superior feild of vision

...and the feenoms beat the eg2's in these areas
-fits more helmets
-most lens choices are completley mirrored as opposed to kinda mirrored like the eg2's
-fits people with medium size faces
-lenses are more durable
-comes with an extra night skiing lense (2008/2009 models only)

...eg2 cons
-fits only people with large large faces
-lenses are not completley mirrored
-not compatible with many helmets because of huge size
-lenses stratch easily

...Feenom cons
-not as huge and head turning

BOTTOM LINE: i say feenoms all the way because i NEED completely mirrored lenses, and i occasionally wear a helmet, and the egs are way too big to fit SOME (not all helmets), and the feenoms are pretty good with helmets...BUT if you can bear to have people see your eyes and dont wear a helmet and want total badass head turning style, go for the eg2's

orange is just an orange lens that comepletley see thru from the outside...the silver chrome is an orange lens that has a silver mirror coating, and from the outside it looks silver and is reflective

Ionized from dragon just means the mirror coating they put on the lenses. These goggles are pretty sick. Just to let you know they are quite big, but that is a good thing. They give you a really large field of view and with them being spherical as well, you really can't beat them as far as the field of view and clarity you will get out of them.

yes, the mirror finish is only when viewed from the outside. look at the last picture in the bottom row and you can see that the lens has a rose tint when you are looking through it. that helps to increase contrast

No.-------------------yeah right!!!!...do you ever look up while ur riding? whenever you look up air will go rushing thru that gap and blow in ur face

these are too big for most helmets, you need a low profile helmet with a high crown that doesnt go very far down the forehead, like the RED mutiny or smith holt...a good example of a BAD fitting helmet would be the RED hi-fi, cuz that has a very very low crown...low crown means that the helmet will push you gogs down on ur face, like the foam will be resting on ur eyes, yeah not fun :-)

These goggles with work with all helmets, but if for some strange reason they don't work with yours, you can always return them.

its not supposed to but i snipped mine

Check out the Smith Knowledge w/ Turbo Fan:http://www.backcountry.com/store/SMI0380/Smith-Knowledge-OTG-Turbo-Fan-Series-Goggles-Mirror-Lens.html

I've seen these worn with a helmet, if you want them bad enough, you could just buy them, and if they don't fit just return them for a full refund. If there's a local place that has them you could try them on, then buy them here so you can get backcountry's awesome return policy if you have any problems.

polarized lens are extra dark, they are not something you want in low/flat light, you'd want a yellow or orange lens for that.

Best for very sunny days in high to extreme light conditions.

You should be fine with these goggles. They don't come down that much right on the nose and they'll fit the helmet fine. I didn't find these goggles to look as large on my face as I did in the picture.Hope that helps.

You can pull them apart, you just stretch the frame a tiny bit and the strap comes out. They definitely aren't MEANT to be removed though because I could see doing this too much causing the frame to stretch permanently.

They should be compatible, your helmet has a really straight brim and nothing that would constrict it. It won't be a tight fit, but you wont be readjusting everything mid run.

All goggles stick out quite a bit from the face. That is the nature of the goggle being able to not fog up and give you good vission while wearing them. If you dont want to look like a bug, stick with a helmet, it is safer anyways.

These goggles will fit your helmet just fine. They shouldn't cover your nose too much. If you have a very small face/nose you might try a smaller goggle but for most people these are totally fine.

Maybe, because these goggles are so HUGE they dont fit with many helmets, but ofcourse you can try. I suggest you buy The Smith Holt Helmet if you really want this goggle, because it has a tall fit and would match with the EG2, but as I sayd - You can try, but I would say the goggle are too big for the Giro Encore 2 helmet. :) Do whatever you want

When I look at the Giro Encore 2 Helmet It looks like the Electric EG2 Goggle will be too big, but of course it depends on the size of the helmet and if you like to have the goggle on the tip of your nose. I bought the helmet in Matte White with the Electric EG1 Chrome Goggle - Chrome Bandana White/Silver Chrome, which can be found at http://www.backcountryoutlet.com/outlet/ELC0096/Electric-EG1-Chrome-Goggle-Chrome.html:)

I just got them and they fit perfectly.
