Another satisfied IOX user here in the PNW!
I can get them to fog here pretty easy but we are talking 32F and raining. After half a day, I get minor fogging in between the inner and outer lens but letting them air dry in the house overnight makes them good to go in the morning.
I am also a fan of the red sensor lens for the PNW flat light.
Great goggle at a decent price....
None of the I/O (I/O, I/Os, I/OX) lenses should be fogging between the glass. This just happened to TWO of my lenses last time I was out. It was obviously moisture inside the lens because the fog went away when taken off my face, that was warmer than outside air.
How the moisture got in there I have no clue. Has to be a bad seal or bad vent. I haven't been in the rain once, washed them in the sink once, nor have I had face plants or tons of face shots. I'm at a loss...... BUT even if I'd been in all of those conditions they still shouldn't fog between the glass.
It didn't happen once all the days of spring riding I've been doing. But the first day in the 20's it happened.
I used to wash my I/O lenses under the faucet with soap and water and only had a fogging issue on one lens after repeatedly washing them after every trip out. I only stopped because smith said it wasn't needed, that I could wipe the insides when completely dry with no issues.
I need to call Smith.
lol... sorry for the ramble..... bottom line is they should not fog between the lenses from what I was told by Smith.
