Internal fogging on double-walled goggles - does any brand do worse or better?

[SchralphMacchio]

Of course this is user error. I should have a 12V desiccating box that houses my entire family’s goggles and move that box from the basement to the RV or truck as we travel. But I don’t.

The issue here is not that I’m storing them wet, it’s that once dried out, they live in their goggle bag, with all our other shit, *in an unconditioned and somewhat humid space* on the west side of the Oregon Cascades. The air between the lenses will equilibrate to that space. When the goggles go directly from that environment to the ski hill they will fog internally. Once they have been hanging over a heating vent in my RV for a night, I don’t have this problem. And I mostly don’t have this problem with other double wall goggles, just my Smith Vices. They basically seem slower to equalize the internal humidity to atmosphere than other goggles.

I think the main thing is ensuring that they are drying out during transit. The process of specifically laying all of the family’s goggles (and spares) around the dashboard, rear view mirror, before each drive up the hill etc seems like such a pain but I guess I don’t have an alternative.

Another note, popping out lenses to aid drying isn’t practical with the Vice frames. Seems like with the Squad Mag frames it is super easy. But then Greg says that the Mag lenses seem to be even slower to equilibrate …

Ah. You're fucked then...

(We have non mag Smiths. Currently the pre mag with the side pivot. And some OG ones with tabs on lens that "key" into frames. A bit of a hassle to change lenses, but learn the knack, m'kay?)

Smith goggles don’t use an anti fog treatment on the inside. They use a mechanical anti fog design of mini ridges.

Is this for specific models? I just bought some Smith Reason OTG and the literature seems to indicate there’s a treatment.

Smith may warranty those lenses. The lens spacer foam is compromised somewhere, or the pressure equalization filter (if it has one), is toast. Try them, sometimes you need to call.

At one point, Smith made the BEST EVER thermal goggle lens - the Vaporator or some such name. Patented. The inner & outer lenses were all bonded using a robotic silicone seal in Woodinville, WA. BC guides horded them, employees too. Sigh, that is now history, too expensive, production moved to UT using what everyone uses: 3M acrylic bonded foam. It works, it's not fool-proof, but Smith are among the better folks at lenses & QC.

Also, your thermal lenses like warm & dry after a day in the PNW. Heater vents (not too hot, eh) work pretty well since they pump dry(er) warm air. Take care of them, they will take care of you kind of deal. And Smith might take care of you (although Vice has been out of production for a long time now). For your next goggle, go big(er), more air volume means less chance to hit dew point and collect moisture, especially in the PNW.

Good luck.

Rinse them with warm water. Seriously. Literally rinse both exterior surfaces and set aside to dry.

This worked like a goddamn charm - only addition is that i put the fuckers on a heat duct in my house to dry. Like new.
