This demonstrates the effect a simple dollar store umbrella has on reducing your thermal signature from ground scanning thermal imagers, and obviously, if used like a normal umbrella with the canopy facing upward, you have total thermal signature blocking from aerial imagers as well. This is important to know for those of us who may find ourselves behind enemy lines with a hostile foreign government hunting us. This is a simple, field expedient, compact method to rapidly reduce your thermal signature to environmentally neutral, and it fits in a standard M16 mag pouch for quick deployment. Thermal signature reduction, escape and evasion, field expedient methods for defeating thermal scopes, thermal drones, thermal helicopters, FLIR.
