Bioinspired metafabric delivers powerful personal cooling by reflecting sunlight and managing sweat

Imagine standing under an intense midday sun, with no shade in sight. The heat is unbearable, and for outdoor workers, athletes, and soldiers, such conditions can quickly lead to heat stress or even life-threatening situations. While air conditioning provides relief indoors, it’s not an option for those constantly exposed to extreme temperatures. Instead of energy-draining systems, the solution may lie in a simple yet powerful innovation: the fabric we wear.
