Using anti-fog inserts are very effective such as these: http://www.ebay.com/itm/8-Anti-Fog-Inserts-for-GoPro-Hero3-Hero2-Hero-by-NoFog-/181051646529?pt=LH_DefaultDomain_0&hash=item2a2784e241

The other ones I linked to are very thin. They tend to fit into very tight spots between the camera and case.
FWIW You often find even smaller desiccant strips/bags in scrap hard disks, along with a tiny air filter.

Desiccant bags absorb water vapour from the air. As they clearly can't have infinite capacity to do so, how do you "dry" them out and store then after they have been exposed the normal moisture in the atmosphere for a while?
When folks make there own anti-fog paper towel inserts, they simply dry them in an oven for a short time and can usually reuse them. Your ordinary desiccant pack is made of silica gel. According to Wikipedia, silica gel can be regenerated by heating it 250 F for a couple hours.
I myself wouldn't try it. It's cheap enough to buy plenty of them.
When I was a telecom tech, we used to have huge bags of silica gel. If you took a hand full of the stuff and poured water on it, the silica would get so hot you couldn't hold it. It could absorb a good amount of water though. I think if you store them in a Ziploc it will keep them fresh until needed. I keep desiccant pack in all of my ammo boxes to keep it dry and they can last a good while if not exposed to fresh air often.
