Think you'd try it? I'm kinda on the fence about this one. Certainly a viable solution for folks that don't wear contacts with goggles or have prescription inserts with goggles.

I wear contacts only when I am riding downhill or moto under my goggles. I like having that still(ish) pocket of air in front my eyes because my contacts dries out and starts shifting after 3-4hrs if i don't re-wet. Although, I realize that a careful balance of air circulation is integral to anti-fog, I feel that the airflap would introduce too much airflow where my contacts would dry out and i'm concerned that the gap can let in dirt/debris and sweat easier.

Or maybe I should just sack up and get PRK and be done with this contacts malarky.

mmm I think it's a catch 22. In MTB, you want protection from wind and dust and mud and stuff. In trials moto, you don't really have to deal with wind unless you're riding in a hurricane and you don't have to deal with dust/dirt unless you're riding right behind somebody else.

IIRC, I've ridden with ill-fitting goggles before, and they fog up MORE than goggles that fit tight to my face. That little bit of gap that they had allowed hot breath up underneath.

I could see this being a great product for when you have to stop and fix your bike or in the lift line, but I'm usually helmet off and goggles around my neck as soon as I hit the bottom.

What is this PRK thing?

I only wear contacts when I wear goggles now. Glasses any other time.

Photorefractive keratectomy (PRK) it doesn't disrupt the cornea as badly as lasik. in lasik the corneal flap never really heals, thusly, when engaged in contact sports, there is theoretically a higher incidence of globe (eye) rupture with trauma if you've had lasik.

but, lasik is well tolerated, folks go back to work next day. PRK is f-ing painful, hence the need to be out a couple days.

In about 6 months or so this company will have their device out for repairing the cornea after lasik. Same founder who produced the lasik procedure. They are an OEM customer of mine gearing up for production and its a cool product to fix just the issue you are concerned with. http://www.avedro.com/lasikxtra Some very cool med-tech coming about in the next few years.

It probably doesn't work as well but I've found that switching my lenses out for double paned (snowmobile) lenses works wonders for fog reduction.

For me I find wearing my goggles makes my helmet feel a bit more secure on my head. Only a minor thing, but I appreciate it nonetheless. Especially when your helmet gets a bit old and the pads get a bit looser. So I'm out.

"AirFlaps also enables the rider to keep his/her goggles on the helmet when putting it on or taking it off. No more goggles hanging on the wrist or on handlebars !"

Yep, because you definitely can't just leave your goggles in-place when you take your helmet off!

I have a couple friends with these and they seem like a good idea. I bought one but haven't put it on yet. I am thinking I will use it more on the dirt bike when struggling on a wet rooty climb than on the DH bike. My friends are using them on the DH bikes and are pretty happy.
