Ment to baffle thermal imaging and sensing systems, the thermal suit consists of a layer of insulation and a thermal emissions system. It has small thermal sensors as various points, which constantly read the surrounding air temperature, and raise or lower the suits external temperature to match. Because it has to block the wearer's thermal emissions, it must be able to function as medium weight climate-control suit. It must also cover the entire body, restricting peripheral vision, covering the ears and hands and generally being a little bulky. The best way to defeat theses suits to install very rapid thermal variations in your environment (for example, have one room be about 30 degrees, while another is about 20)
