Abstract The rapid development of global urbanization has exacerbated the urban heat island effect and electromagnetic radiation pollution. However, existing fabrics fail to provide both effective personal thermal management interference (EMI) shielding. To address this challenge, an asymmetric gradient porous fabric (AGPF) is developed using a delayed evaporation‐induced phase separation strategy. AGPF consists polystyrene‐block‐poly(ethylene‐ran‐butylene)‐block‐polystyrene (SEBS) transversely oriented liquid metal (LM) networks with wrinkled structures at bottom. Due complete sedimentation metal, SEBS maintains excellent solar reflectivity 93.9% atmospheric window infrared emissivity 94.7%. Upon activation by pre‐stretching, LM imparts high electrical conductivity enhanced stretchability AGPF, resulting in EMI shielding effectiveness 80.6 dB heating performance. Outdoor cooling tests further confirmed that achieves sub‐ambient ≈9.5 °C. Moreover, exhibits dynamically tunable performance across strain range 0% 200%, adapting complex outdoor environments. design provides advanced solution protect individuals from dual threats posed effects
