I tried searching for a while, but couldn't come up with much. I deer hunt in northern Michigan and usually wear a face mask or balaclava most of the time. The problem I have is my binoculars fogging up as I'm looking through them. This happens due to my warm breath. They do "unfog" after a minute or so, but its so annoying, that I don't use the binos as often as I probably should. I've tried holding my breath some, putting anti-fog on the lenses, etc..., but nothing seems to work effectively. How do you guys that hunt in the cold make this work? If it matters, I don't wear any glasses when hunting.
Thanks.

Keep them inside your coat, if they are warm when you pull them out your breath won't condense on them.

I've tried two products that seem to help quite a bit with this. One is Fog Zero and the other is Clarity DeFog-it. Both are safe for sport optics.

Toothpaste usually contains an abrasive. May be harmless as a defogging agent but I would avoid it because there are safer, liquid based defogging concoctions available. Dive shops usually have one or two products on the shelf.

Sage advise. I would never use anything abrasive on coated optics

Yeah, Dawn will help, as will several commericial equivalents, some of which may be repackaged Dawn. But they also tend to compromise the optics slightly. This happens because the added layer doesn't function like another lens coating. Instead it tends to scatter light.
Other than not breathing on your binoculars, the best solution is to buy binoculars with a built-in moisture-resistant lens coating. Some older coatings had the same disadvantage as Dawn or other liquid coatings, but the recent built-in coatings don't compromise the view, since they're engineered to work with the other lens coatings. Bushnell's Rainguard is a good example.

I put it on glasses and SCBA masks at teh fire dept and goggles... we fog up quick in fire situations... its the only thing that comes close to being reliable.... A shame its as high as it is, but I"m going to buy another 50 or so dollars worth of it shortly... running low.

If the rubber eyecups (if present) are extended fold them down and get a cold air space between your eyes and the glass.

Thanks. Don't wear a balaclava while you're glassing. Travis

No. Rain-X though is not safe for coated optics. Says so right on the bottle.

For glassing in the cold and dealing with breath, you pretty much just have to learn a conscious habit of blowing down and away on the exhale. You can't just let the warm breath float around your face. Blow it out and down, away from you.

Fogging? You need to stop watching things through the neighbor's windows for a starter.

No problem with that here. Neighbor has a figure like Humpty Dumpty.
