Near Infrared (NIR) Signature Management Technology is used by the U.S. Department of Defense to prevent detection by NIR Image Converters. These photocathode devices do not detect temperatures, but rather infrared radiation variances. NIR-compliant uniforms use a special fabric that allows soldiers to appear at the same radiation level as the surrounding terrain, thus making them more difficult to detect.
To ensure that our military personnel avoid any danger connected to the use of uniforms, Propper has clearly labeled products on this website that are approved for military operations. Similarly, products based on the Army Combat Uniform (ACU) design without NIR technology are also labeled to prevent any error in purchasing.
