Harvey has now come out in a set of hoodies and scarves that block thermal radiation from the infrared scanners drones use. Wearing the fabric would make that part of the body look black to a drone, so the image would appear like disembodied legs

His designs seem to be no more than a political statement and provide no true protection from surveillance.

To truly hide your image from IR surveillance would require a complete body covering. Such a covering would likely kill the person wearing it do to over heating of the body.

To hide the body’s waste heat the clothing must reflect the heat back to the body.

If you look at the photos accompanying the article you will notice that the hoodie only covers the head and shoulders. The rest of the body is uncovered and free to shed body heat.

Ive often wondered if a ‘space blanket’ lining of a gillie suit would block all IR, or perhaps a ‘shake and bake’ type enclosure like I used to carry on wildland fires.

If you were to just mask part of the body heat, you would break up your outline, like the camouflage pattern they used to paint on warships. If you got enough people together wearing them, it might be difficult to pick out one person in a crowd.
