downstairs: xria: Err, I can see the thermal imaging being defeated by clothing, but their example must be fake surely - how it would it reduce the thermal signature on exposed parts of the skin (face, arms, etc.)?

My guess is that they're also wearing special makeup all over their body?  That could answer the whole "WTF is with their eyes" a few posters here questioned.


1. It's not "special makeup" it's a pale chick with a lot of eyeliner. It's not everyone's thing, but I dig it.

2. Either it's a stupid "fashion" thing(as opposed to a functional military thing), or the clothes are only covering certain things so that the picture can display the difference.

davidab: somehow are fantastic at hiding a heat signature.


You make it sound like magic and not so much science.

It's simple. There are several materials that will not pass or emit much IR.

http://en.wikipedia.org/wiki/Emissivity

http://en.wikipedia.org/wiki/Low_emissivity

Reflection has a lot to do with it, any metal that has a good shine not considerably warm will reflect and appear "invisible".

Many optics, such as eyeglasses will look black on IR camera's(which are set to display white = hot), even with no tint. Large bodies of water are black, but you can detect IR through humidity. They pass visible light, but not so much IR wavelengths that these camera's work on.(hence the dark spots on some eyes in your picture). Interestingly, they (glass) can pass IR from remote controls and such because they work on a different wavelength than what most things emit. You can actually "blind" IR camera's with enough IR LED's, there are guides on lifehacker or one of those sites for disassembling remotes to do this.

And of course, as others mentioned, you can also use a barrier/insulator to mask your radiation, but that tends to build up heat, and once they warm up can emit IR as well as anything else.

Until they make that clothing illegal to posses.

To everyone who wants to do away with the second amendment; that would set a very dangerous precedent. After that; any amendment in the bill of rights would be subject to revision or removal.

Wait, what? How the fark does a t-shirt mask the thermal heat from the wearer's legs and head? I cry bullschitt.

/Image is hot like a bombed civilian.

They've been wearing this for years. They just couldn't sell it for $500.
