<p>Polymer coatings with high performance and cost-effectiveness play a vital role in protective textiles with water-resistant yet water-vapor-permeable performance, which is highly demanded in applications such as outdoor garments, medical dressings, and wearable electronics. However, current polymer-coated fabrics can hardly meet the requirements of high-performance protective textiles due to their unsatisfactory breathability. Herein, the fabric coating is endowed with a net-like structure containing abundant interconnected through-pores, enabling exceptional breathability based on a humidity-induced networking strategy. By tuning water cluster condensation and droplet arrangement through the humidity control, polyurethane networks with tiny open holes and full coverage can be self-assembled directly on common woven fabrics. Followed by the coating with a low-surface-energy fluorinated polymer, network-coated fabrics are equipped with robust liquid repellency. By virtue of the net-like architectures of polymer-coated fabrics with through holes (porosity of 62.5%), reduced pore size (9.42&#xa0;μm), and robust hydrophobicity (140.1°), the resultant coated fabrics exhibit the impressive breathability (2854&#xa0;g m^-2 d^-1) and enhanced waterproofness (269&#xa0;mmH₂O). We envision that this work will open ample opportunities to design and develop next-generation coated textiles for various applications.</p> Graphical Abstract <p></p>
