Abstract
Sorption-based atmospheric water harvesting (AWH) offers a decentralized, sustainable solution to global freshwater scarcity, enabling clean water in diverse environments. However, translating ideal sorption properties of small-scale materials into practical, large-scale systems faces critical kinetic challenges. Here, we conceptualize a hierarchical textile fiber for wearable AWH, addressing the scaling limitations of traditional sorbents. These fibers feature an open-pore surface topology and internal hierarchical pore structures, which accelerate surface vapor liquefaction and subsequent water transport, demonstrating exceptional water uptake and rapid sorption kinetics across varying relative humidity (RH). When woven into textiles, the fibers maintain efficient vapor diffusion through their macroporous, breathable architecture, achieving a 3- to 10-fold improvement over traditional sorbents at scale. We engineered a wearable prototype combining the AWH textile with a portable collector, achieving 3.76 to 7.45 literswater per kilogramsorbent per day and collecting 410 to 894 milliliters across 20 to 80% RH. By overcoming kinetic limitations, our study advances AWH toward scalability and wearability with implications for global water sustainability.

Abstract
Accelerating progress towards Sustainable Development Goal (SDG) 6 by 2030 requires a decentralized, off-grid water supply strategy that performs across various climates. Here we report a field-portable, solar-powered, litre-scale atmospheric water-harvesting system built through a cross-scale material-to-system design that unites sorbent–device configuration with climate-aware operation. In this system, hierarchically porous cellulosic gel fabrics are assembled into compact, channelized cartridges and integrated with a solar-concentrated, transport-matched modular system, overcoming the long-standing trade-off between portability and productivity. A humidity-adaptive protocol compensates for humidity disparity and sustains output across diverse conditions. Outdoor trials delivered 1.3 l of water in Austin with a dual module (~62% relative humidity, 4.7 l m−2 d−1) and 4.3 l m−2 d−1 in the Chihuahuan Desert (~26% relative humidity), and operation persisted under cloudy conditions (~0.4 sun) with 310 ml of water produced per module. Geospatial analysis showed peak annual yields co-locate with water stress hotspots. This portable, modular platform provides climate-robust, litre-scale drinking water and a practical accelerator and equity lever for SDG 6.
