I just purchased a pair of costa black fins with 580 glass lens and have noticed they fog up a little on very hot days. I was wondering if anyone had any opinion on some anti-fog products that have worked good for you. I have read some good stuff on car crap and the fogtech products? Anyone use them before? 

I have costas that fog up once in a while.  I will slide them down my nose and they clear pretty quickly.  You have to let some air circulate between your face and the glass.  I have never used a defogger.

I know what works on a diving mask...

Take the Buff off your nose . . . .

Is what it is.  Works like a charm.  probably best when you don't have a chest cold though.

It's best if you don't drink milk first. Really hard to see thru those lenses then.

How about a bag of cheetos? 

Cat crap.

No, really!  Not actual poop...  I use it on ski goggles and it's the best I've found.

Fogging up is a problem that I'm not sure even spit 
can properly solve.

I've also got 580G Costas and have had to slide them
off my face, or down my nose when they fog up.

Pain, but it is inevitable that they'll fog. I'm not sure
there is any one solution that will keep the clarity 
and d**n the fogginess to the netherworld.

I used Nikon Fog Eliminator but it appears it is no longer available.  I shoot a lot of archery and these wipes help a lot especially when walking thru the woods on hot, humid, no wind days.  They last a while if you put them back into the protective wrapper.

Thanks everyone. I ended up ordering cat crap, just because I don't really feel like putting shaving cream and spitting in my $250 glasses.

For a ridiculously named product it really does well.  I know a few divers and lots of skiers that use it.  Even with the freezing temps and sweating/heavy breathing in skiing it works wonders.

Did it work,  I have the same problem with my costas and it's driving me crazy

Bailey hasn't been on here in over a year. However, @Master Bait'r has been active in the last month. Since he was the poster the introduced the product maybe he'll chime in and give us a current update. I'm interested as well. 

Spit works now availble as Quick Spit anti fog by Jaws.

I don’t know the OP, but Cat Crap does work darn well for ski goggles while snowmaking- the worst fogging conditions on the planet.  

There is no such thing as fog free glasses. When you sweat the humidity fogs them up. There is a solution for skiers and they have fans built in on both sides. Glasses that allow the most air flow will obviously fog less. Lots of suckers buy fogfree spray snakeoil and it doesn't do anything. The great reviews from people are indeed true. They believe their product works but they are just sitting around and not sweating.
