How it works:
Nighthawkinlight's thermal camouflage works by using a special fabric that actively cools itself below the temperature of its surroundings. Unlike traditional thermal camouflage that eventually heats up due to body heat, this material remains colder than its environment, effectively masking the wearer's thermal signature.
