This is a special fabric that can be reversed to show two different camouflage patterns, like woodland on one side and desert on the other. Its core feature is a middle layer that blocks infrared light, making the wearer harder to spot with night vision equipment. This infrared-blocking layer is made from a polyurethane film placed between two thin, porous ePTFE films, with one of the ePTFE films having a special coating that contains infrared-suppressing chemicals.
Why it matters: The increasing prevalence and sophistication of short-wave infrared (SWIR) imaging technology since 2013 makes effective SWIR camouflage more critical. Advances in IR-suppressing additives or film manufacturing processes may also have improved feasibility.
