Passive
radiative cooling holds transformative potential
for achieving
energy-free thermal management, yet its effectiveness in hot and humid
climates has remained severely limited by humidity-induced performance
degradation, restricting cooling powers to only 10–20 W m<sup>–2</sup>. Here, we report a metal–organic-framework-engineered
metatextile (MEMT) that overcomes this longstanding challenge through
the monolithic integration of radiative and evaporative cooling. The
MEMT achieves high daytime cooling powers of 153 and 170 W m<sup>–2</sup> under 70% and 20% relative humidity, respectively, an order-of-magnitude
improvement over conventional radiative cooling technologies in humid
climates. This performance is enabled by the synergistic combination
of high solar reflectance (94.9%), strong mid-infrared emissivity
(96.6%), and autonomous atmospheric moisture harvesting with a water
uptake capacity of 153.3 mg g<sup>–1</sup>. Critically, the
textile harvests all required moisture autonomously from ambient air,
eliminating any dependence on external water input and enabling fully
self-sustained operation. Its woven architecture ensures mechanical
durability, breathability, and manufacturing scalability across wearable,
architectural, and industrial applications. This approach enables
autonomous passive cooling under challenging climatic conditions and
may contribute to reducing global cooling energy consumption and associated
carbon emissions.
